Saleem Abdulrasool c5e0099ffc ARM64: add an explicit cast to silence a silly warning
GCC 4.8 complains with:
  warning: enumeral and non-enumeral type in conditional expression

Although this is silly and harmless in this case, add an explicit cast to
silence the warning.

Juergen Ributzka 48c8c07d0a [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>.

Reid Kleckner 2d4a69e9c9 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.

Jim Grosbach 83b44e1e21 Fix to support properly cleaning up failed address sinking against constants
As it turns out the source of the sunkaddr can be a constant, in which case
there is not an instruction to delete, causing the cleanup code introduced in
r204833 to crash. This patch adds a dynamic check to ensure the deleted value is
in fact an instruction and not a constant.

Jim Grosbach e4fef71981 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.

Jim Grosbach cad4cd6c9e SelectionDAG: Don't constant fold target-specific nodes.
FoldConstantArithmetic() only knows how to deal with a few target independent
ISD opcodes. Bail early if it sees a target-specific ISD node. These node do
funny things with operand types which may break the assumptions of the code
that follows, and there's no actual folding that can be done anyway. For example,
non-constant 256 bit vector shifts on X86 have a shift-amount operand that's a
128-bit v4i32 vector regardless of what the first operand type is and that breaks
the assumption that the operand types must match.

Kevin Enderby c296ecd96c 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.

Chad Rosier 9ce19fb65c [AArch64] Implement the isTruncateFree API.
In AArch64 i64 to i32 truncate operation is a subregister access.

This allows more opportunities for LSR optmization to eliminate
variables of different types (i32 and i64).

Quentin Colombet 0b1a5584d6 [DAGCombiner] DAG combine does not know how to combine indexed loads with
sign/zero/any extensions. However a few places were not checking properly the
property of the load and were turning an indexed load into a regular extended
load. Therefore the indexed value was lost during the process and this was
triggering an assertion.

Justin Holewinski 30d56a7b86 [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).
