 - One functionality change, '\\' in a name is now printed as a hex
   escape instead of "\\\\". This is consistent with other users of
   PrintEscapedString.

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.

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

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.

id could end up being wrong mostly because of

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.

Fix PR2634.  Create new virtual registers from spills early so that we
can give it the same stack slot as the spilled interval if it is folded.
This prevents the fold/unfold code from pointing to the wrong register.
