Subject: rename decorateName -> DecorateCygMingName, make it assert if not
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c08872ec60fc1b8d475d910139c10a12df0f3564;p=oota-llvm.git

rename decorateName -> DecorateCygMingName, make it assert if not
cygming, make the two callers only call it if cygming.  Other minor
cleanups.
