Duncan P. N. Exon Smith 04384959c2 Linker: Share a single Metadata map for the lifetime of IRMover ... Cache the result of mapping metadata nodes between instances of IRLinker (i.e., for the lifetime of IRMover). There shouldn't be any real functional change here, but this should give a major speedup. I had loaned this to Mehdi when he tested performance of r266446, and the two patches together gave a 10x speedup in metadata mapping. llvm-svn: 266579		2016-04-17 23:30:31 +00:00
