...
forwarding any uses). GlobalDCE can also do this, but is only
run at -O3.

Change tests from "opt %s" to "opt < %s" so that opt doesn't see the
...
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

If the target of an alias has internal linkage, then the
...
alias can be morphed into the target. Implement this
transform, and fix a crash in the existing transform at
the same time.
