58b9662000 Simplify nested strconcats in X86 td files since strconcat can take more than 2 arguments.

152bee45fa Mark all the _REV instructions as not having side effects. They aren't really emitted by the backend, but it reduces the number of instructions in the output files with unmodelled side effects to make auditing easier.

7c37abcace Add explicit VEX_L tags to all 256-bit instructions. This will allow us to remove code from the code emitters that examined operands to set the L-bit.

8d3031fa46 Rename fma4 intrinsics to just fma since they are now used for both FMA4 and FMA3. Autoupgrade support coming in a separate commit.

685b86b007 Use sse_load_f32/64 for scalar FMA3 intrinsic patterns instead of 128-bit loads to match instruction behavior.

02e5a00a70 Remove fadd(fmul) patterns for FMA3. This needs to be implemented by paying attention to FP_CONTRACT and matching @llvm.fma which is not available yet. This will allow us to enablle intrinsic use at least though.

6343cc814e Tidy up. Remove trailing spaces and fix the worst of the 80 column violations.

194da7364d Added FMA3 Intel instructions. 
I disabled FMA3 autodetection, since the result may differ from expected for some benchmarks.
I added tests for GodeGen and intrinsics.
I did not change llvm.fma.f32/64 - it may be done later.

44a5136fac Separate the concept of having memory access in operand 4 from the concept of having the W bit set for XOP instructons. Removes ORing W-bits in the encoder and will similarly simplify the disassembler implementation.

33091db89a Change FMA4 memory forms to use memopv* instead of alignedloadv*. No need to force alignment on these instructions. Add a couple testcases for memory forms.

e066262284 Fix load size for FMA4 SS/SD instructions. They need to use f32 and f64 size, but with the special handling to be compatible with the intrinsic expecting a vector. Similar handling is already used elsewhere.

add tests for vfmaddsd.
