After https://reviews.llvm.org/rL355317 we noticed that quite a decent amount of code redeclares builtins (memcpy in particular, I believe reduced from an MSVC header) with a calling convention specified. This gets particularly troublesome when the user specifies a new 'default' calling convention on the command line. When looking to add a diagnostic for this case, it was noticed that we had 3 other diagnostics that differed only slightly. This patch ALSO unifies those under a 'select'. Unfortunately, the order of words in ONE of these diagnostics was reversed ("'thiscall' calling convention" vs "calling convention 'thiscall'"), so this patch also standardizes on the former. Differential Revision: https://reviews.llvm.org/D59560 Change-Id: I79f99fe7c2301640755ffdd774b46eb44526bb22 llvm-svn: 356663
