Maybe I'm missing something obvious, but could one of you explain to me
the comment of that proc, which is

# Return 1 if target has x86_64 registers - either amd64 or x32.
# x32 target identifies as x86_64-*-linux*, therefore it cannot be determined
# just from the target string.

If I understand correctly, is_amd64_regs_target should return 1 when using the
x32 abi, as well as when using the standard amd64 abi.  The comment says an x32
target has an x86_64-* triplet... so can't we just check the triplet, and return
1 if it's x86-64-*?
