David Blaikie b735b4d6db DebugInfo: remove target-specific Frame Index handling for DBG_VALUE MachineInstrs 
Frame index handling is now target-agnostic, so delete the target hooks
for creation & asm printing of target-specific addressing in DBG_VALUEs
and any related functions.

Andrew Trick de2109eb4c Machine Model: Add MicroOpBufferSize and resource BufferSize. 
Replace the ill-defined MinLatency and ILPWindow properties with
with straightforward buffer sizes:
MCSchedMode::MicroOpBufferSize
MCProcResourceDesc::BufferSize

These can be used to more precisely model instruction execution if desired.

Disabled some misched tests temporarily. They'll be reenabled in a few commits.

Bill Wendling 4a7a408eaa Don't cache the instruction and register info from the TargetMachine, because 
the internals of TargetMachine could change.

Bill Wendling f77190855d Cache the TargetLowering info object as a pointer. 
Caching it as a pointer allows us to reset it if the TargetMachine object
changes.

Ahmed Bougacha b1a4d9da3b Make SubRegIndex size mandatory, following r183020. 
This also makes TableGen able to compute sizes/offsets of synthesized
indices representing tuples.

Andrew Trick ad6d08ac6f Order CALLSEQ_START and CALLSEQ_END nodes. 
Fixes PR16146: gdb.base__call-ar-st.exp fails after
pre-RA-sched=source fixes.

Patch by Xiaoyi Guo!

This also fixes an unsupported dbg.value test case. Codegen was
previously incorrect but the test was passing by luck.

Rafael Espindola 227144c23c Remove the MachineMove class. 
It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.

I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

Rafael Espindola 1b09836bc3 Change getFrameMoves to return a const reference. 
To add a frame now there is a dedicated addFrameMove which also takes
care of constructing the move itself.
