2a6d9eb10b Change this DAGCombine to build AND of SHR instead of SHR of AND; this matches the ordering we prefer in instcombine. Part of rdar://9562809. 
The potential DAGCombine which enforces this more generally messes up some other very fragile patterns, so I'm leaving that alone, at least for now.

a1000742d2 Fix emission of PPC64 assembler on non-darwin platforms by splitting 
VK_PPC_{HA,LO}16 into darwin and gas variants.

Darwin wants {ha,lo}16(symbol) while gnu as wants symbol@{ha,l}.

1dd94bbfa1 SplitCriticalEdge can sometimes split the edge from an invoke to a landing 
pad, separating the exception and selector calls from the new lpad.  Teaching
it not to do that, or to properly adjust the CFG afterwards, is out of
scope because it would require the other edges to the landing pad to be split
as well (effectively).  Instead, just recover from the most likely cases
during inlining.  The best long-term solution is to change the exception
representation and commit to either requiring or not requiring the more
complex edge-splitting logic;  this is just a shorter-term hack.

f1e2b23dfa Move TableGen's register bank classes to their own source file. 
I'll be moving some more code there to gather all of the
register-specific stuff in one place. Currently it is shared between
CodeGenTarget and RegisterInfoEmitter.

The plan is that CodeGenRegisters can compute the full register bank
structure while RegisterInfoEmitter only will handle the printing part.

2a9d1ca9c2 Remove custom allocation order boilerplate that is no longer needed. 
The register allocators automatically filter out reserved registers and
place the callee saved registers last in the allocation order, so custom
methods are no longer necessary just for that.

Some targets still use custom allocation orders:

ARM/Thumb: The high registers are removed from GPR in thumb mode. The
NEON allocation orders prefer to use non-VFP2 registers first.

X86: The GR8 classes omit AH-DH in x86-64 mode to avoid REX trouble.

SystemZ: Some of the allocation orders are omitting R12 aliases without
explanation. I don't understand this target well enough to fix that. It
looks like all the boilerplate could be removed by reserving the right
registers.

- cfi directives are not inserted at the right location or in the right order.
- The source MachineLocation for the cfi directive that changes the cfa register
  to $fp should be MachineLocation::VirtualFP.
- A PROLOG_LABEL that marks the beginning of cfi_offset directives for
  callee-saved register is emitted even when no callee-saved registers are
  saved.
- When a callee-saved double precision register is saved, two cfi_offset
  directives, one for each of the paired single precision registers, should be
  emitted.
