59fcd68657 Make CVTDQ2PS instruction use SSE2 predicate instead of SSE1. No functional change because there are no patterns in the instructions. Also fix a typo in a comment.

cb686400fb X86: Rename the CLMUL target feature to PCLMUL. 
It was renamed in gcc/gas a while ago and causes all kinds of
confusion because it was named differently in llvm and clang.

d09b64fc25 Instruction scheduling itinerary for Intel Atom. 
Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT.

Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches.

Adds a test to verify that the scheduler is working.

Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP.

ba73cefabb Mark non-VEX forms of PCLMUL instructions as requiring SSE2 to be enabled along with CLMUL. That's required for the XMM registers to be valid for integer data. Doesn't change any behavior since the CLMUL instructions don't have patterns yet.

63bb77ebe7 Mark non-VEX forms of AES instructions as requiring SSE2 to be enabled along with AES. Since that's required for the XMM registers to be valid for integer data. Doesn't change any behavior though since you can't use an intrinsic with an illegal type anyway. Just makes it consistent with the VEX forms.

93e29adc2f Many of the SSE patterns should not be selected when AVX is available. This led to the following code in X86Subtarget.cpp 
if (HasAVX)
    X86SSELevel = NoMMXSSE;

This is so patterns that are predicated on hasSSE3, etc. would not be selected when avx is available. Instead, the AVX variant is selected.
However, this breaks instructions which do not have AVX variants.

The right way to fix this is for the SSE but not-AVX patterns to predicate on something like hasSSE3() && !hasAVX().
Then we can take out the hack in X86Subtarget.cpp. Patterns which do not have AVX variants do not need to change.

However, we need to audit all the patterns before we make the change. This patch is workaround that fixes one specific case,
the prefetch instructions. rdar://10538297

9380919dc5 - Handle special scalar_to_vector case: splats. Using a native 128-bit 
shuffle before inserting on a 256-bit vector.
- Add AVX versions of movd/movq instructions
- Introduce a few COPY patterns to match insert_subvector instructions.
This turns a trivial insert_subvector instruction into a register copy,
coalescing the xmm into a ymm and avoid emiting on more instruction.

8174253484 Implement support for the bizarre 3DNow! encoding (which is unlike anything 
else in X86), and add support for pavgusb.  This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.

If someone else is interested in banging out the rest of the 3DNow! 
instructions, it should be quite easy now.
