be done incrementally and intermixed with the adding of more
AVX instructions. This is a first step in that direction

fddb7667ca Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field. 
When a target instruction wants to set target-specific flags, it should simply
set bits in the TSFlags bit vector defined in the Instruction TableGen class.

This works well because TableGen resolves member references late:

class I : Instruction {
  AddrMode AM = AddrModeNone;
  let TSFlags{3-0} = AM.Value;
}

let AM = AddrMode4 in
def ADD : I;

TSFlags gets the expected bits from AddrMode4 in this example.

6d1cd1cd04 Separate out the AES-NI instructions from the SSE4.2 instructions. Add 
a new subtarget option for AES and check for the support.  Add "westmere"
line of processors and add AES-NI support to the core i7.

Add a couple of TODOs for information I couldn't verify.

357be7f289 Renumber SSE execution domains for better code size. 
SSEDomainFix will collapse to the domain with the lower number when it has a
choice. The SSEPackedSingle domain often has smaller instructions, so prefer
that.

70feca409e Teach TableGen to understand X.Y notation in the TSFlagsFields strings. 
Remove much horribleness from X86InstrFormats as a result. Similar
simplifications are probably possible for other targets.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99539 91177308-0d34-0410-b5e6-96231b3b80d8

352aa503fa Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain crossings. 
On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register
in a different domain than where it was defined. Some instructions have
equvivalents for different domains, like por/orps/orpd.

The SSEDomainFix pass tries to minimize the number of domain crossings by
changing between equvivalent opcodes where possible.

This is a work in progress, in particular the pass doesn't do anything yet. SSE
instructions are tagged with their execution domain in TableGen using the last
two bits of TSFlags. Note that not all instructions are tagged correctly. Life
just isn't that simple.

The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline
issue handled by NEONMoveFixPass. This pass may become target independent to
handle both.

044be39090 Fixed the SS42AI template for the SSE 4.2 instructions with TA prefix so it does 
not get an "Unknown immediate size" assert failure when used.  All instructions 
of this form have an 8-bit immediate.  Also added a test case of an example
instruction that is of this form.
