Add support for the 'xsave', 'xrstor', 'xsaveopt', 'xgetbv', and 'xsetbv'
instructions. I reimplemented this from scratch based on the Intel
manuals and the existing support for handling the fxsave and fxrstor
instructions. This will let us use these instructions natively with GCC
rather than hardcoding the opcodes in hex.
