Starting to refactor Target to separate out code that's needed to fully describe
target machine from those that are only needed by codegen. The goal is to
sink the essential target description into MC layer so we can start building
MC based tools without needing to link in the entire codegen.

First step is to refactor TargetRegisterInfo. This patch added a base class
MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to
separate register description from the rest of the stuff.

PPC doesn't supported VLA with large alignment. This was
formerly rejected by the FE, so asserted in the BE; now the FE only
warns, so we treat it as a legitimate fatal error in PPC BE.
This means the test for the feature won't pass, so it's xfail'd.

The PPC MFCR instruction implicitly uses all 8 of the CR
registers. Currently it is not so marked, which leads to
VCMPEQ instructions that feed into it getting deleted.
If it is so marked, local RA complains about this sequence:
vreg = MCRF CR0
MFCR <kill of whatever preg got assigned to vreg>
All current uses of this instruction are only interested in
one of the 8 CR registers, so redefine MFCR to be a normal
unary instruction with a CR input (which is emitted only as
a comment). That avoids all problems. 7739628.

Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe what
the variable actually tracks.

N.B., several back-ends are using "HasCalls" as being synonymous for something
that adjusts the stack. This isn't 100% correct and should be looked into.
