Jim Grosbach 7a37166a7a X86: Enable ISel of 16-bit MOVBE instructions. 
When the MOVBE instructions are available, use them for 16-bit endian
swapping as well as for 32 and 64 bit.

The patterns were already present on the instructions, but weren't being
matched because the operation was unconditionally marked to 'Expand.'
Change that to be conditional on whether the MOVBE instructions are
available. Use 'rolw' to implement the in-register version (32 and 64
bit have the dedicated 'bswap' instruction for that).

Patch by Louis Gerbarg <lgg@apple.com>.
