Explicitly request unsigned enum types when desired
The underlying type of all plain enums in MSVC is 'int', even if the
enumerator contains large 32-bit unsigned values or values greater than
UINT_MAX. The only way to get a large or unsigned enum type is to
request it explicitly with the C++11 strong enum types feature.
However, since LLVM isn't C++11 yet, I had to add a conditional
LLVM_ENUM_INT_TYPE to Compiler.h to control its usage.
The motivating true positive for this change is compiling PointerIntPair
with MSVC for win64. The PointerIntMask value is supposed to be pointer
sized value of all ones with some low zeros. Instead, it's truncated to
32-bits! We are only saved later because it is sign extended back in
the AND with int64_t, and we happen to want all ones.
This silences lots of -Wmicrosoft warnings during a clang self-host
targeting Windows.

DebugInfo: Wrap section data and relocs together for dwarf dumping support
This is a small step that may enable some simplifications in producer
(DWARFContext) and consumer (DWARFCompileUnit and other places) by
making a more complete abstraction around the data and relocations for a
section. Small initial steps could include simple changes such as
passing the pair to DWARFCompileUnit's ctor rather than passing the data
and relocs separately. I don't intend to pursue any such changes
immediately, however.
The motivation for doing this now is that type unit dumping will need to
deal with these data+reloc pairs moreso than the existing dumping
support has needed to associate the data as type unit sections are named
the same (debug_types) and comdat group folded. So to implement dumping
and reloc handling we'll need a mapping of section->data+relocs.

X86: Use R_X86_64_TPOFF64 for FK_Data_8
Summary:
LLVM would crash when trying to come up with a relocation type for
assembly like:
movabsq $V@TPOFF, %rax
Instead, we say the relocation type is R_X86_64_TPOFF64.
Fixes PR17274.

SROA: Handle casts involving vectors of pointers and integer scalars.
SROA wants to convert any types of equivalent widths but it's not possible to
convert vectors of pointers to an integer scalar with a single cast. As a

of cast used to be an edge case but has become common with SLP vectorization.

SelectionDAG: Teach the legalizer to split SETCC if VSELECT needs splitting too.
The Type Legalizer recognizes that VSELECT needs to be split, because the type
is to wide for the given target. The same does not always apply to SETCC,
because less space is required to encode the result of a comparison. As a result
VSELECT is split and SETCC is unrolled into scalar comparisons.
This commit fixes the issue by checking for VSELECT-SETCC patterns in the DAG
Combiner. If a matching pattern is found, then the result mask of SETCC is
promoted to the expected vector mask for the given target. This mask has usually
te same size as the VSELECT return type (except for Intel KNL). Now the type
legalizer will split both VSELECT and SETCC.
This allows the following X86 DAG Combine code to sucessfully detect the MIN/MAX
pattern. This fixes PR16695, PR17002, and <rdar://problem/
14594431>.

Reapply "SLPVectorizer: Handle more horizontal reductions (disabled)""
Reapply r191108 with a fix for a memory corruption error I introduced. Of
course, we can't reference the scalars that we replace by vectorizing and then
call their eraseFromParent method. I only 'needed' the scalars to get the
DebugLoc. Just store the DebugLoc before actually vectorizing instead. As a nice
side effect, this also simplifies the interface between BoUpSLP and the
HorizontalReduction class to returning a value pointer (the vectorized tree
root).

PR16726: extend rol/ror matching
C-like languages promote types like unsigned short to unsigned int before
performing an arithmetic operation. Currently the rotate matcher in the
DAGCombiner does not consider this situation.
This commit extends the DAGCombiner in the way that the pattern
(or (shl ([az]ext x), (*ext y)), (srl ([az]ext x), (*ext (sub 32, y))))
is folded into
([az]ext (rotl x, y))
The matching is restricted to aext and zext because in this cases the upper
bits are either undefined or known. Test case is included.
This fixes PR16726.
