78d1e95201 R600: Promote i64 stores to v2i32
Now we need only one 64-bit pattern for stores.

93ea1378d2 R600/SI: Stop using i128 as the resource descriptor type
Having i128 as a legal type complicates the legalization phase.  v4i32
is already a legal type, so we will use that instead.

This fixes several piglit tests.

These are sometimes created by the shrink to boolean optimization in the
globalopt pass.

f95b162188 R600: Fix handling of vector kernel arguments
The SelectionDAGBuilder was promoting vector kernel arguments to legal
types, but this won't work for R600 and SI since kernel arguments are
stored in memory and can't be promoted.  In order to handle vector
arguments correctly we need to look at the original types from the LLVM IR
function.

3986785046 R600/SI: Use -verify-machineinstrs for most tests
We can't enable the verifier for tests with SI_IF and SI_ELSE, because
these instructions are always followed by a COPY which copies their
result to the next basic block.  This violates the machine verifier's
rule that non-terminators can not folow terminators.

38d5e1c36d R600/SI: Lower BUILD_VECTOR to REG_SEQUENCE v2
Using REG_SEQUENCE for BUILD_VECTOR rather than a series of INSERT_SUBREG
instructions should make it easier for the register allocator to coalasce
unnecessary copies.

v2:
  - Use an SGPR register class if all the operands of BUILD_VECTOR are
    SGPRs.

692ee102eb R600: Add 64-bit float load/store support
* Added R600_Reg64 class
* Added T#Index#.XY registers definition
* Added v2i32 register reads from parameter and global space
* Added f32 and i32 elements extraction from v2f32 and v2i32
* Added v2i32 -> v2f32 conversions

Tom Stellard:
  - Mark vec2 operations as expand.  The addition of a vec2 register
    class made them all legal.

73e44d8ae4 R600/SI: Report unaligned memory accesses as legal for > 32-bit types
In reality, some unaligned memory accesses are legal for 32-bit types and
smaller too, but it all depends on the address space.  Allowing
unaligned loads/stores for > 32-bit types is mainly to prevent the
legalizer from splitting one load into multiple loads of smaller types.

4efccd0fb1 R600: Use EXPORT_RAT_INST_STORE_DWORD for stores on Cayman
We were using RAT_INST_STORE_RAW, which seemed to work, but the docs
say this instruction doesn't exist for Cayman, so it's probably safer
to use a documented instruction instead.
