Fix PR2986: do not use a potentially illegal

Add a RM pseudoreg for the rounding mode, which
allows ppcf128->int conversion to work with
DeadInstructionElimination.  This is now turned
off but RM is harmless.  It does not do a complete
job of modeling the rounding mode.

Revert marking MFCR as using all 7 CR subregisters;
while correct, this caused the problem in PR 2964,
plus the local RA crash noted in the comments.
This was needed to make DeadInstructionElimination,
but as we are not running that, it is backed out
for now.  Eventually it should go back in and the
other problems fixed where they're broken.

Fix a FIXME: in ReplaceNodeWith, if the new node
is morphed by AnalyzeNewNode into a previously
processed node, and different result values of
that node are remapped to values with different
nodes, then we could end up using wrong values
here [we were assuming that all results remap
to values with the same underlying node].  This
seems theoretically possible, but I don't have
a testcase.  The meat of the patch is in the
changes to AnalyzeNewNode/AnalyzeNewValue and
ReplaceNodeWith.  While there, I changed names
like RemapNode to RemapValue, since it really
remaps values.  To tell the truth, I would be
much happier if we were only remapping nodes
(it would simplify a bunch of logic, and allow
for some cute speedups) but I haven't yet worked
out how to do that.

Support for constant islands in the ARM JIT.

Since the ARM constant pool handling supercedes the standard LLVM constant
pool entirely, the JIT emitter does not allocate space for the constants,
nor initialize the memory. The constant pool is considered part of the
instruction stream.

Likewise, when resolving relocations into the constant pool, a hook into
the target back end is used to resolve from the constant ID# to the
address where the constant is stored.

For now, the support in the ARM emitter is limited to 32-bit integer. Future
patches will expand this to the full range of constants necessary.

fix prototype of print, it is (llvm/Pass.h):

instead of

Avoid calls to setSubgraphColor in release mode. They generate lots of error messages and slow down compilation.

Fix darwin ppc llvm-gcc build breakage: intercept
ppcf128 to i32 conversion and expand it into a code
sequence like in LegalizeDAG.  This needs custom
ppc lowering of FP_ROUND_INREG, so turn that on and
make it work with LegalizeTypes.  Probably PPC should
simply custom lower the original conversion.

Fix a testcase provided by Bill in which the node

Fix a nasty miscompilation of 176.gcc on linux/x86 where we synthesized
a memset using 16-byte XMM stores, but where the stack realignment code
didn't work.  Until it does (PR2962) disable use of xmm regs in memcpy
and memset formation for linux and other targets with insufficiently
aligned stacks.

Have TableGen emit setSubgraphColor calls under control of a -gen-debug
flag.  Then in a debugger developers can set breakpoints at these calls
to see waht is about to be selected and what the resulting subgraph
looks like.  This really helps when debugging instruction selection.
