If the intent is to specifically check codegenprepare, should have an IR->IR
test in test/Transforms/CodeGenPrepare.
I don't know whether the -disable-lsr output is the best or not, but based on
the name of the test I would assume this would try to document the actual
result, not with the special flag.
Also this test shouldn't have been using -O3 (it barely does anything and -O2
is the default)
