Support AVX-512 instructions with a writemask in delocate.

Browse Source 
AVX-512 adds a new text instruction syntax to x86-64 assembly to specify
the writemask registers and the merge-masking vs zeroing-masking signal.

This change causes these tokens to be passed through.

Patch by Jeff McDonald.
