The correct name of the type in LLVM assembly is "x86_mmx". Also remove
the reST label "t_x86mmx" because it was unused anyway.

itself and teach it to convert between the non-const and const variants.
De-templatetize its usage in APIs to just use the const variant which
always works for those use cases. Also, rename its implementation to
reflect that it is an iterator over *users* not over *uses*.
This is a step toward providing both iterator and range support for
walking the *uses* distinct from the *users*. In a subsequent patch this
will get renamed to make it clear that this is an adaptor over the
fundamental use iterator.

using a full uint16_t with the flag value... which happens to be
0 or 1. Update the class for bool values and rename functions slightly.

Looks like llvm-readobj is the only customer of this code, and apparently
there's no test to cover this function. I'll write it after finishing
plumbing from llvm-objdump to there.

Some unreachable code is only "sometimes unreachable" because it
is guarded by a configuration value that is determined at compile
time and is always constant. Sometimes those represent real bugs,
but often they do not. This patch causes the reachability analysis
to cover such branches even if they are technically unreachable
in the CFG itself. There are some conservative heuristics at
play here to determine a "configuration value"; these are intended
to be refined over time.

Summary:
Our usual definition of max_align_t wouldn't match up with MSVC if it
was used in a template argument.

Currently this code is duplicated across visitSHL, visitSRA and visitSRL. The
plan is to add rotates as clients to this new function.
There is no functional change intended here.

ProcessGDBRemote::GetAuxvData obtains the auxv from a remote gdbserver (via a binary-data packet), and returns the data as a DataBufferSP.
The patch includes a small fix to GDBRemoteCommunicationClient::SendPacketsAndConcatenateResponses() to support binary file format packet returns (by not assuming each binary packet is a null-terminated string when concatenating them).

Use llvm::sys::fs::make_absolute to get an absolute path before
matching. Also, allow "." directories to enable testing. ".." is still
not supported, and will require crossing file system boundaries to
implement correctly.

Summary:
This is needed to allow MSVC's <atomic> header to properly parse.
It uses _Atomic as a class-id.

This fails an "isa<> used with null pointer" assert during a clang-cl
self-host on Windows. This was caused by r202769, and I'm currently
reducing a test case.

This change uses a fixed known offset for the Linux i386 DR0 register.
This change also undoes the 32-bit wordsize change from r169645 that
revolved around being 32-bit/64-bit friendly in
WriteRegOperation::Execute within the Linux ProcessMonitor.cpp. I ran
all the tests on x86_64 Linux with no failures. I also ran some simple
tests with 32-bit Linux exe on x86_64 host and 32-bit linux exe on
i686 32-bit host and these worked fine.
Note (from Todd): the UserData struct in the Linux i386 register
context (only used by Linux i386 host running Linux 32-bit inferior)
is out of sync with what shows up in the sys/user.h for an 32-bit
Linux build (per an earlier change of mine to make it look more like
x86_64 host running x86 exe). I think we should (1) make i386 Linux
targets run using the same register context (and correct ones) on i386
and x86_64 linux hosts if that is possible, and (2) we could use some
tests around the register handling, particularly to verify things like
DR0 registers are in the right spots on host/target combos that we can
verify vs. known correct values.
