67283b8a5e objdump: identify WoA WinCOFF/ARM correctly
Since LLVM currently only supports WinCOFF, assume that the input is WinCOFF
rather than another type of COFF file (ECOFF/XCOFF).  If the architecture is
detected as thumb (e.g. the file has a IMAGE_FILE_MACHINE_ARMNT magic) then use
a triple of thumbv7-windows.

This allows for objdump to properly handle WoA object files without having to
specify the target triple manually.

c0b8743f35 MC: rework static_assert to be MSVC compatible
Visual Studio does not permit referencing a structure member as a static field

Visual Studio and other compilers.

c30a52807f Support: Move OnDiskHashTable from clang to llvm
This introduces clang's Basic/OnDiskHashTable.h into llvm as
Support/OnDiskHashTable.h. I've taken the opportunity to add doxygen
comments and run the file through clang-format, but other than the
namespace changing from clang:: to llvm:: the API is identical.

e1a38f7041 [ARM64] Fix "Cannot select" for vector ctpop
The commit of r205855:

Author: Arnold Schwaighofer <aschwaighofer@apple.com>
Date:   Wed Apr 9 14:20:47 2014 +0000

    SLPVectorizer: Only vectorize intrinsics whose operands are widened equally

    The vectorizer only knows how to vectorize intrinics by widening all operands by
    the same factor.

    Patch by Tyler Nowicki!

exposed a backend bug causing a regression (Cannot select ctpop).

The commit msg is a bit confusing because the patch actually changes the
behavior for the loop-vectorizer as well.  As things got refactored into a
helper ctpop got snuck in to the trivially-vectorizable helper which is now
used by both vectorizers.  In other words, we started seeing vector-ctpops in
the backend.

This change makes ctpop LegalizeAction::Expand for the types not supported by
the byte-only CNT instruction.  We may be able to custom-lower these later to
a single CNT but this is to fix the compiler crash first.

Fixes <rdar://problem/16578951>

b902acb16c Allow diagnostic handlers to check for optimization remarks.
Summary:
When optimization remarks are enabled via the driver flag -Rpass, we
should allow the FE diagnostic handler to check if the given pass name
needs a diagnostic.

We were unconditionally checking the pattern defined in opt's
-pass-remarks flag. This was causing the FE to not emit any diagnostics.

NaN encoding (-mnan=2008). This patch also adds support for parsing
'.nan legacy' and '.nan 2008' assembly directives. The handling of
these directives should match GAS' behaviour i.e., the last directive
in use sets the ELF header bit (EF_MIPS_NAN2008).

fef8e383eb ARM64: use 32-bit moves for constants where possible.
If we know that a particular 64-bit constant has all high bits zero, then we
can rely on the fact that 32-bit ARM64 instructions automatically zero out the
high bits of an x-register. This gives the expansion logic less constraints to
satisfy and so sometimes allows it to pick better sequences.

Came up while porting test/CodeGen/AArch64/movw-consts.ll: this will allow a
32-bit MOVN to be used in @test8 soon.

c90bd4a882 [mips] Add calling convention tests covering O32, N32, and N64.
Summary:
I had difficulty finding tests for the N32 and N64 ABI so I've added a
collection of calling convention tests based on the document MIPS ABIs
Described (MD00305), the MIPSpro N32 Handbook, and the SYSV ABI. Where the
documents/implementations disagree, I've used GCC to resolve the conflict.

A few interesting details:
* For N32, LLVM uses 64-bit pointers when saving $ra despite pointers being
  32-bit. I've yet to find a supporting statement in the ABI documentation but
  the current behaviour matches GCC.

* For O32, the non-variable portion of a varargs argument list is also subject
  to the rule that floating-point is passed via GPR's (on N32/N64 only the
  variable portion is subject to this rule). This agrees with GCC's behaviour
  and the SYSV ABI but contradicts part of the MIPSpro N32 Handbook which talks about O32's behaviour.

* The N32 implementation has the wrong callee-saved register list.
  (I already have a fix for this but will commit it as a follow-up).

I've left RUN-TODO lines in for O32 on MIPS64. I don't plan to support this case
for now but we should revisit it.

Add support for emitting .file records.  This is mostly a quality of
implementation change (more complete support for COFF file emission) that was
noticed while working on COFF file emission for Windows on ARM.

A .file record is emitted as a symbol with storage class FILE (103) and the name
".file".  A series of auxiliary format 4 records follow which contain the file
name.  The filename is stored as an ANSI string and is padded with NULL if the
length is not a multiple of COFF::SymbolSize (18).

09256c5bb5 [ARM64,C++11] Clean up the ARM64 LOH collection pass.
