Subject: In the TD pass, don't iterate over the scalar map to find the globals, iterate over
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=34741cf0ddf947132781a42a1613ba20c1d8b9c1;p=oota-llvm.git

In the TD pass, don't iterate over the scalar map to find the globals, iterate over
the globals directly.  This doesn't save any substantial time, however, because the
globals graph only contains globals!
