Authentication-results: sourceware.org; auth=none

   The attached patch revises the tests for the filds and fists
mnemonics to use the assembly...

filds mem(%rip); fists mem(%rip)

and the test for the fildq and fistq mnemonics to use the assembly...

fildq mem(%rip); fistpq mem(%rip)

which will assemble for both 64-bit and 32-bit mode. This is required
to avoid "ambiguous instructions require an explicit suffix" errors
from the clang-based assembler in Xcode 7. The change also has the
side-benefit of allowing the legacy GNU assembler from Xcode 6.3 or
earlier to properly detect that the filds, fists, fildq and fistq
mnemonics are available on x86_64-apple-darwin. Bootstrapped tested on
x86_64-apple-darwin14 against the Apple Inc version cctools-870, GNU
assembler version 1.38 and on x86_64-apple-darwin15 against the new
clang-based assembler.
Okay for gcc trunk?
                Jack
