[LTO] Support Statistics Summary: I thought -Xlinker -mllvm -Xlinker -stats worked at some point but maybe it never did. For clang, I believe that stats are printed from cc1_main. This patch also prints them for LTO, specifically right after codegen happens. I only looked at the C API for LTO briefly to see if this is a good place. Probably there are still cases where this wouldn't be printed but it seems to be working for the common case. I also experimented putting this in the LTOCodeGenerator destructor but that didn't trigger for me because ld64 does not destroy the LTOCodeGenerator.
