New Revision: 342805

URL: http://llvm.org/viewvc/llvm-project?rev=342805&view=rev
Log:
Similar to the handling of darwin target triples, strip the version
numbers off of freebsd target triples, when generating the name of the
ABI list file for check-cxx-abilist target.

Also remove unnecessary parentheses in the regex for darwin, and
slightly reword the comment.
