Daniel Dunbar 5d98824615 MC: Eliminate MC{Fragment,{Section,Symbol}Data}::getAddress.

Daniel Dunbar 5caf2ff561 MC: Fix refacto in MCExpr evaluation, I mistakenly replaced a fragment address with a symbol address.
- This fixes the integrated-as nightly test regressions.

Evan Cheng b07a29ecd4 Disable folding loads into tail call in 32-bit PIC mode. It can introduce illegal code like this:
addl    $12, %esp
        popl    %esi
        popl    %edi
        popl    %ebx
        popl    %ebp
        jmpl    *__Block_deallocator-L1$pb(%esi)  # TAILCALL

The problem is the global base register is assigned GR32 register class. TCRETURNmi needs the registers making up the address mode to have the GR32_TC register class.

The *proper* fix is for X86DAGToDAGISel::getGlobalBaseReg() to return a copy from the global base register of the machine function rather than returning the register itself. But that has the potential of causing it to be coalesced to a more restrictive register class: GR32_TC. It can introduce additional copies and spills. For something as important the PIC base, it's not worth it especially since this is not an issue on 64-bit.

Torok Edwin 4bbfdd41ea Fix memory leak in liveintervals: the destructor for VNInfos must be called,
otherwise the SmallVector it contains doesn't free its memory.
In most cases LiveIntervalAnalysis could get away by not calling the destructor,
because VNInfos are bumpptr-allocated, and smallvectors usually don't grow.
However when the SmallVector does grow it always leaks.

This is the valgrind shown leak from the original testcase:

Chris Lattner db1ac3cf3e Switch SDTUnaryArithWithFlags to being modeled as a two-result

like:

---
>                 // 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.

These instructions are only needed for codegen, so I've removed all the

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

Bob Wilson cc0a2a75a0 Change VST1 instructions for loading Q register values to operate on pairs
of D registers.  Add a separate VST1q instruction with a Q register
source operand for use by storeRegToStackSlot.

Daniel Dunbar de04b3f62c MC: Switch to using MCInst fragments to do relaxation.
Also, both MCMachOStreamer and MCAssembler are now target independent!

Daniel Dunbar 86face8333 MC: Add TargetAsmBackend::MayNeedRelaxation, for checking whether a particular instruction + fixups might need relaxation.

Daniel Dunbar a9ae3ae698 MC: Add TargetAsmBackend::WriteNopData and use to eliminate some target dependencies in MCMachOStreamer and MCAssembler.

Daniel Dunbar e0c43577c1 MC: Add TargetAsmBackend::RelaxInstruction callback, and custom X86 implementation.

Daniel Dunbar 16cbe95dd6 MC: Tweak MCInstFragment to include the encoded data and fixups, so that we don't need to recompute them during relaxation. I will revisit this once all the other pieces of fast relaxation are in place.
