This makes it possible for STABS entries to reference the debug info
contained in the LTO-compiled output.

ld64 emits an N_OSO reflecting the modtime of the newly created object
file. Instead of copying this behavior, I thought it would be nicer to
zero out the modtime of the object file -- that way the output binary
remains reproducible.

I'm not sure how to test the file mtime within llvm-lit -- GNU and BSD
`stat` take different command-line arguments. I've omitted the check for
now.
