[PATCH] D59534: Enable tail call in MemCpyOptimization

[Eli Friedman via Phabricator via llvm-commits]

Rerunning the analysis at some point after memcpyopt definitely makes sense.  I'm not sure where exactly you'd put it, though... I guess after memcpyopt, nothing is really likely to create new tail calls, so just sticking it after memcpyopt might be fine.   Maybe interesting to gather statistics for a few different placements, though.

Actually performing tail recursion elimination after loop optimizations is probably a bad idea, so we might want to split the pass.
