Summary:
As discussed on lldb-dev, this patch moves some LLDB tests into a hierarchy that more closely
resembles the commands we use in the LLDB interpreter. This patch should only move tests
that use the command interpreter and shouldn't touch any tests that primarily test the SB API.

This patch makes `re` an alias for `register`. Currently `re<TAB>` gives
you the choice between `register` and `reproducer`. Given that you use
`register` a lot more often, it should win for the common substring.

Add a convenience 'expectedFailureNetBSD' decorator and mark all tests
currently failing on NetBSD with it. Also skip a few tests that hang
the test suite. This should establish a baseline for the test suite
and get us closer to enabling tests on buildbot. This will help us
catch regressions while we still have a lot of work to do to get tests
working.
It seems that there are also some flaky tests. I am going to address
them later on.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Windows
Summary:
1) When ReadRegister is called with a null register into on Windows, rather than crashing due to an access violation, simply return false. Not all registers and properties will be read or calculated correctly, but that is consistent with other platforms that also return false in that case
2) Update a couple of tests to reference pr37995 as their reason for failure since it is much more accurate. Support for floating point registers doesn't exist on Windows at all, rather than having issues.

Summary: They all correspond to bugs that are already logged and I've added the appropriate (or most appropriate) bug numbers. This leaves only a handful of failing tests.

The test "test_fp_special_purpose_register_read" in TestRegisters.py
fails on Darwin machines configured to use an out-of-tree debugserver.
The error message is: 'register read ftag' returns expected result, got
'ftag = 0x80'. This indicates that the debugserver in use is too old.
This commit introduces a decorator which can be used to skip tests which
rely on having a just-built debugserver. This resolves the issue:
$ ./bin/llvm-dotest -p TestRegisters.py -v
1 out of 617 test suites processed - TestRegisters.py
Test Methods: 7
Success: 6

This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.
For each test (should be eventually: each test configuration) a
separate build directory is created and we execute
make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test
In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.
Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

Summary:
New linux kernels (on systems that support the XSAVES instruction) will
not update the inferior registers unless the corresponding flag in the
XSAVE header is set. Normally this flag will be set in our image of the
XSAVE area (since we obtained it from the kernel), but if the inferior
has never used the corresponding register set, the respective flag can
be clear.
This fixes the issue by making sure we explicitly set the flags
corresponding to the registers we modify. I don't try to precisely match
the flags to set on each write, as the rules could get quite complicated
-- I use a simpler over-approximation instead.
This was already caught by test_fp_register_write, but that was only
because the code that ran before main() did not use some of the register
sets. Since nothing in this test relies on being stopped in main(), I
modify the test to stop at the entry point instead, so we can be sure
the inferior did not have a chance to access these registers.

Normal customer devices won't be able to run these tests, we're hoping to get
a public facing bot set up at some point. Both devices pass the testsuite without
any errors or failures.
I have seen some instability with the armv7 test runs, I may submit additional patches
to address this. arm64 looks good.
I'll be watching the bots for the rest of today; if any problems are introduced by
this patch I'll revert it - if anyone sees a problem with their bot that I don't
see, please do the same. I know it's a rather large patch.
One change I had to make specifically for iOS devices was that debugserver can't
create files. There were several tests that launch the inferior process redirecting
its output to a file, then they retrieve the file. They were not trying to test
file redirection in these tests, so I rewrote those to write their output to a file
directly.

Normal customer devices won't be able to run these devices, we're hoping to get
a public facing bot set up at some point.
There will be some smaller follow-on patches. The changes to tools/lldb-server are
verbose and I'm not thrilled with having to skip all of these tests manually.
There are a few places where I'm making the assumption that "armv7", "armv7k", "arm64"
means it's an ios device, and I need to review & clean these up with an OS check
as well. (Android will show up as "arm" and "aarch64" so by pure luck they shouldn't
cause problems, but it's not an assumption I want to rely on).

The FXSAVE member `ftw` (FPU Tag Word) was given the wrong size (8-bit)
instead of the correct width (16-bit) as per the x87 Programmer's
Manual. Adjust this to ensure that we print out the complete value for
the register.

Summary:
This also removes magic rename code, which caused the channel to be
called "linux" when built on a linux machine, and "freebsd" when built
on a freebsd one, which seems unnecessary - registering a new channel is
sufficiently simple now that if we wish to log something extremely
os-specific, we can just create a new channel. None of the current
categories seem very specific to one OS or another.

This reverts commit rL280668 because the register tests fail on i386
Linux.
I investigated a little bit what causes the failure - there are missing
registers when running 'register read -a'.
This is the output I got at the bottom:
"""
...
Memory Protection Extensions:
bnd0 = {0x0000000000000000 0x0000000000000000}

bnd2 = {0x0000000000000000 0x0000000000000000}
bnd3 = {0x0000000000000000 0x0000000000000000}
unknown:
2 registers were unavailable.
"""
Also looking at the packets exchanged between the client and server:
"""

...
"""
The bndcfgu and bndstatus registers don't have the 'Memory Protections
Extension' set. I looked at the code and it seems that that is set
correctly.
So I'm not sure what's the problem or where does it come from.
Also there is a second failure related to something like this in the
tests:
"""
registerSet.GetName().lower()
"""
For some reason the registerSet.GetName() returns None.

Summary:
The Intel(R) Memory Protection Extensions (Intel(R) MPX) associates pointers
to bounds, against which the software can check memory references to
prevent out of bound memory access.
This patch allows accessing the MPX registers:
* bnd0-3: 128-bit registers to hold the bound values,
* bndcfgu, bndstatus: 64-bit configuration registers,
This patch also adds read/write tests for the MPX registers in the register
command tests and adds a new subdirectory for MPX specific tests.
