Chandler Carruth dd5d86d992 Remove the very substantial, largely unmaintained legacy PGO ... infrastructure. This was essentially work toward PGO based on a design that had several flaws, partially dating from a time when LLVM had a different architecture, and with an effort to modernize it abandoned without being completed. Since then, it has bitrotted for several years further. The result is nearly unusable, and isn't helping any of the modern PGO efforts. Instead, it is getting in the way, adding confusion about PGO in LLVM and distracting everyone with maintenance on essentially dead code. Removing it paves the way for modern efforts around PGO. Among other effects, this removes the last of the runtime libraries from LLVM. Those are being developed in the separate 'compiler-rt' project now, with somewhat different licensing specifically more approriate for runtimes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191835 91177308-0d34-0410-b5e6-96231b3b80d8		2013-10-02 15:42:23 +00:00
