bc1fd917f0 Move the segmented stack switch to a function attribute
This removes the -segmented-stacks command line flag in favor of a
per-function "split-stack" attribute.

e7ef041ba4 For the ARM integrated assembler add checking of the
alignments on vld/vst instructions.  And report errors for
alignments that are not supported.

While this is a large diff and an big test case, the changes
are very straight forward.  But pretty much had to touch
all vld/vst instructions changing the addrmode to one of the
new ones that where added will do the proper checking for
the specific instruction.

FYI, re-committing this with a tweak so MemoryOp's default
constructor is trivial and will work with MSVC 2012. Thanks
to Reid Kleckner and Jim Grosbach for help with the tweak.

d95a78ca52 [mips] NotMips64 predicate is really a test for 32-bit GPR's.
Summary:
Similarly, the HasMips64 on the 64-bit move InstAlias is a test for 64-bit
GPR's.

No functional change.

feb96be96e [mips] Switch the MIPS-III and MIPS-IV assembler tests to use -mcpu=mips4.
Summary:
It is now the smallest superset for these ISA's.

FeatureMips4 now contains FeatureFPIdx since [ls][dw]xc1 were added in MIPS-IV.
Made the FPIdx feature bit lowercase so that it can be used in the -mattr option.

Depends on D3274

d631cc4563 [ARM64] Fix immediate cost calculation for types larger than i64.
The immediate cost calculation code was hitting an assertion in the included
test case, because APInt was still internally 128-bits. Truncating it to 64-bits
fixed the issue.

Fixes <rdar://problem/16572521>.

6a6b4d5dfa Revert "For the ARM integrated assembler add checking of the alignments on vld/vst instructions. And report errors for alignments that are not supported."
It doesn't build with MSVC 2012, because MSVC doesn't allow union
members that have non-trivial default constructors.  This change added
'SMLoc AlignmentLoc' to MemoryOp, which made MemoryOp's default ctor
non-trivial.

This reverts commit r205930.

afb4ef3549 Add support for load folding of avx1 logical instructions
AVX supports logical operations using an operand from memory. Unfortunately
because integer operations were not added until AVX2 the AVX1 logical
operation's types were preventing the isel from folding the loads. In a limited
number of cases the peephole optimizer would fold the loads, but most were
missed. This patch adds explicit patterns with appropriate casts in order for
these loads to be folded.

The included test cases run on reduced examples and disable the peephole
optimizer to ensure the folds are being pattern matched.

77f268945e [NVPTX] Add preliminary intrinsics and codegen support for textures/surfaces
This commit adds intrinsics and codegen support for the surface read/write and texture read instructions that take an explicit sampler parameter. Codegen operates on image handles at the PTX level, but falls back to direct replacement of handles with kernel arguments if image handles are not enabled. Note that image handles are explicitly disabled for all target architectures in this change (to be enabled later).
