Remove explicit casts to std::string now that there is no overload resolution
issues in the TargetData ctors.

This is part of the on-going work on PR 761.

Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses.  This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.

This fixes PR 759.

Make the CBE and V9 backends create their own, since they're the only ones that use it.

1. Treat FMOVD as a copy instruction, to help with coallescing in V9 mode
2. When in V9 mode, insert FMOVD instead of FpMOVD instructions, as we don't
   ever rewrite FpMOVD instructions into FMOVS instructions, thus we just end
   up with commented out copies!
This should fix a bunch of failures in V9 mode on sparc.

Add a new option to indicate we want the code generator to emit code quickly,not spending tons of time microoptimizing it.  This is useful for an -O0style of build.

3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.
