This patch removes the lower layers of the minidump parsing code from
the MinidumpParser class, and replaces it with the minidump parser in
llvm.
Not all functionality is already avaiable in the llvm class, but it is
enough for us to be able to stop enumerating streams manually, and rely
on the minidump directory parsing code from the llvm class.
This also removes some checked-in binaries which were used to test error
handling in the parser, as the error handling is now done (and tested)
in llvm. Instead I just add one test that ensures we correctly propagate
the errors reported by the llvm parser. The input for this test can be
written in yaml instead of a checked-in binary.

This patch begins the process of migrating the "minidump" plugin to the
minidump parser in llvm. The llvm parser is not fully finished yet, but
even now, a lot of things can be switched over. The gradual migration
process will allow us to easier detect if things break than doing a big
one-step migration. Doing it early will allow us to make sure that the
llvm parser fits the use case that we need in lldb.
In this patch I start with the various minidump constants, which have
their llvm equivalent. It doesn't contain any functional changes. The
diff just reflects the different naming of things in llvm.

In this patch I add support for ARM and ARM64 break pad files. There are two flavors of ARM: Apple where FP is R7, and non Apple where FP is R11. Added minimal tests that load up ARM64 and the two flavors or ARM core files with a single thread and known register values in each register. Each register is checked for the exact value.
This is a fixed version of: https://reviews.llvm.org/D49750
The changes from D49750 are:
Don't init the m_arch in the Initialize call as a system info isn't required. This keeps the thread list, module list and other tests from failing
Added -Wextended-offsetof to Xcode project so we catch use extended usages of offsetof before submission
Fixed any extended offset of warnings

This reverts commit r338734 (and subsequent fixups in r338772 and
r338746), because it breaks some minidump unit tests and introduces a
lot of compiler warnings.

Some new files were committed to the repository but not added
to the CMakeLists.txt, so this patch fixes the build.

Most non-local includes of header files living under lldb/sources/
were specified with the full path starting after sources/. However, in
a few instances, other sub-directories were added to include paths, or
Normalize those few instances to follow the style used by the rest of
the codebase, to make it easier to understand.

plugin in SystemInitializerFull
Summary:
This plugin resembles the already existing Windows-only Minidump plugin.
The WinMinidumpPlugin uses the Windows API for parsing Minidumps
while this plugin is cross-platform because it includes a Minidump
parser (which is already commited)
It is able to produce a backtrace, to read the general puprose regiters,
inspect local variables, show image list, do memory reads, etc.
For now the only arches that this supports are x86_32 and x86_64.
This is because I have only written register contexts for those.
Others will come in next CLs.
I copied the WinMinidump tests and adapted them a little bit for them to
work with the new plugin (and they pass)
I will add more tests, aiming for better code coverage.
There is still functionality to be added, see TODOs in code.

Summary:
This, like the x86_64 case, reads the register values from the minidump
file, and emits a binary buffer that is ordered using the offsets from
the RegisterInfoInterface argument. That way we can reuse an existing
register context.
Added unit tests.

Summary:
This is a register context converter from Minidump to Linux reg context.
This knows the layout of the register context in the Minidump file
(which is the same as in Windows FYI) and as a result emits a binary data
buffer that matches the Linux register context binary layout.
This way we can reuse the existing RegisterContextLinux_x86_64 and
RegisterContextCorePOSIX_x86_64 classes.

Summary:
This is a Minidump parsing code.
There are still some more structures/data streams that need to be added.
The aim ot this is to be used in the implementation of
a minidump debugging plugin that works on all platforms/architectures.
Currently we have a windows-only plugin that uses the WinAPI to parse
the dump files.
Also added unittests for the current functionality.
