Add 64-bit (GR64) versions of some instructions (which are not
described in their SSE forms, but are described in AVX)

Move some SIMD fragment code into X86InstrFragmentsSIMD so that the
utility classes can be used from multiple files.  This will aid
transitioning to a new refactored x86 SIMD specification.

llvm-svn: 108213

TableGen fragment refactoring.

Move some utility TableGen defs, classes, etc. into a common file so
they may be used my multiple pattern files.  We will use this for
the AVX specification to help with the transition from the current
SSE specification.
