This is a general clean up of the PowerPC ABI. Address several problems and
bugs including making sure that the TOS links back to the previous frame,
that the maximum call frame size is not included twice when using frame
pointers, no longer growing the frame on calls, double storing of SP and
a cleaner/faster dynamic alloca.

Fix ppc64 epilog bug.

Properly transfer kill / dead info.

Fix the PPC regressions last night

llvm-svn: 31752

Rework PPC64 calls. Now we have a LR8/CTR8 register which the PPC64 calls
clobber. This allows LR8 to be save/restored correctly as a 64-bit quantity,
instead of handling it as a 32-bit quantity.

the code is actually located above the 4G boundary.

For PR786:
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Completely eliminate def&use operands. Now a register operand is EITHER a
def operand or a use operand.

Handle callee saved registers in dwarf frame info (lead up to exception

Fix some comments.

The PPC64 JIT needs register numbers to encode instructions.

In 64-bit mode, 64-bit GPRs are callee saved, not 32-bit ones.

Fix rewriting frame offsets with ixaddr instructions, which implicitly shift
the offset two bits to the left.

Rename OR4 -> OR. Move some PPC64-specific stuff to the 64-bit file

Gaar! Don't use r11 for CR save/restore, use R0. R11 can be register
