I've committed svn r159570 which adds a -stop-after=<passname> option to llc. 
For example, you can run it with -stop-after=loop-reduce to write out the IR
after LSR.  This is still a work in progress.  In particular, the output file
format is expected to change to a YAML file, but it should be good enough to
start writing some LSR unit tests.
