385e4e9d98 Handle directive arguments with * in them.
Some of the CFI directives from upstream include expressions such as:

   .cfi_adjust_cfa_offset 32*5+8

(Also the latest version of peg moves the go generate line to
delocate.peg.go.)

05a8434484 Support AVX-512 instructions with a writemask in delocate.
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.

f64a6eeaf0 Switch to new delocate tool.
Most importantly, this version of delocate works for ppc64le. It should
also work for x86-64, but will need significant testing to make sure
that it covers all the cases that the previous delocate.go covered.

It's less stringtastic than the old code, however the parser isn't as
nice as I would have liked. I thought that the reason we put up with
AT&T syntax with Intel is so that assembly syntax could be somewhat
consistent across platforms. At least for ppc64le, that does not appear
to be the case.
