I can see the value of doing tests like this on the side, but the
tests in "make check" are intentionally simple regression tests that
check only one "thing" at a time.

Maybe this would be better served by a llc/clang-cc1 option to link a
MCAsmStreamer to an asm parser and then the final streamer? We could
then use that option on a bot building llvm-testsuite for example.
