Hi,

currently we have memcmp-1.c and sanity-check-pure-c-1.c (ASan 
testsuite) output pattern test failures on x86_64-apple-darwin14. This 
patch adjusts their expecting patterns to match real ones.

Tested by me on x86_64-unknown-linux-gnu and by Dominique on 
x86_64-apple-darwin14.

Ok to apply?
