Subject: [RewriteStatepointsForGC] Replace std::map with DenseMap
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ca6245c5541321f08974b4908617e3e8aebbab1a;p=oota-llvm.git

[RewriteStatepointsForGC] Replace std::map with DenseMap

I'd done the work of extracting the typedef in a previous commit, but didn't actually change it.  Hopefully this will make any subtle changes easier to isolate.
