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.

This patch removes the logic for resolving paths out of FileSpec and
updates call sites to rely on the FileSystem class instead.

Summary:
The ObjectFile class was used to determine the architecture of a running
process by inspecting it's main executable. There were two issues with
this:
- it's in the wrong layer
- the call can be very expensive (it can end up computing the crc of the
whole file).
Since the process is running on the host, ideally we would be able to
just query the data straight from the OS like darwin does, but there
doesn't seem to be a reasonable way to do that. So, this fixes the
layering issue by using the llvm object library to inspect the file.
Since we know the process is already running on the host, we just need
to peek at a few bytes of the elf header to determine whether it's 32-
or 64-bit (which should make this faster as well).
Pretty much the same logic was implemented in
NativeProcessProtocol::ResolveProcessArchitecture, so I delete this
logic and replace calls with GetProcessInfo.

Summary:
ProcFileReader is the cause of the dependency from Host to ProcessLinux
module. Since it's interface is also obsolete (ReadIntoDataBuffer is
trivially replaceable by llvm::MemoryBuffer functions and
ProcessLineByLine is trivially implementable with StringRefs), instead
of moving it around I'm planning to obliterate it. This is the first
step, where I remove a couple of occurences in linux/Host.cpp, and
modernize some code around that.
I have introduced linux/Support.h, which holds two utility functions
now, whose resposibility is to construct the appropriate proc file names
-- the only useful feature of ProcFileReader.
I add a couple of tests for these functions, and for
Host::GetProcessInfo. It's worth noting that these are the first
host-specific unit tests in lldb.
