Delete CC_Default and use the target default CC everywhere Summary: Makes functions with implicit calling convention compatible with function types with a matching explicit calling convention. This fixes things like calls to qsort(), which has an explicit __cdecl attribute on the comparator in Windows headers. Clang will now infer the calling convention from the declarator. There are two cases when the CC must be adjusted during redeclaration: 1. When defining a non-inline static method. 2. When redeclaring a function with an implicit or mismatched convention. Fixes PR13457, and allows clang to compile CommandLine.cpp for the Microsoft C++ ABI. Excellent test cases provided by Alexander Zinenko!

Renamed and changed the wording of warn_cconv_ignored As discussed in D64780 the wording of this warning message is being changed to say 'is not supported' instead of 'ignored', and the diag ID itself is being changed to warn_cconv_not_supported. llvm-svn: 366368

[Sema] Emit a better diagnostic when variable redeclarations disagree We referred to all declaration in definitions in our diagnostic messages which is can be inaccurate. Instead, classify the declaration and emit an appropriate diagnostic for the new declaration and an appropriate note pointing to the old one. This fixes PR24116. llvm-svn: 242190
