0d53d0a634 Switch SDTUnaryArithWithFlags to being modeled as a two-result 
ISD node.  The only change in the generated isel code are comments
like:

<                 // Src: (X86dec_flag:i16 GR16:i16:$src)
---
>                 // Src: (X86dec_flag:i16:i32 GR16:i16:$src)

because now it knows that X86dec_flag returns both an i16 (for the result)
and an i32 (for EFLAGS) in this case.  Wewt.

test run permformance numbers say as to whether it helps.

9df76f18b4 Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain crossings. 
This is work in progress. So far, SSE execution domain tables are added to
X86InstrInfo, and a skeleton pass is enabled with -sse-domain-fix.

a9eb6a6987 add some accessors to callsite/callinst/invokeinst to check 
for the noinline attribute, and make the inliner refuse to
inline a call site when the call site is marked noinline even
if the callee isn't.  This fixes PR6682.

a88ac90daf Don't back past debug info intrinsics; SCEVExpander's strategy 
for ignoring debug info intrinsics everywhere else is to advance
past them, and it needs to be consistent.

195c570fd3 Fix VLDMQ and VSTMQ instructions to use the correct encoding and address modes. 
These instructions are only needed for codegen, so I've removed all the
explicit encoding bits for now; they should be set in the same way as the for
VLDMD and VSTMD whenever we add encodings for VFP.  The use of addrmode5
requires that the instructions be custom-selected so that the number of
registers can be set in the AM5Opc value.
