[DebugInfo] Add calling conventions to DISubroutineType Summary: This should have been a very simple change, but it was greatly complicated by the construction of new Decls during IR generation. In particular, we reconstruct the AST function type in order to get the implicit 'this' parameter into C++ method types. We also have to worry about FunctionDecls whose types are not FunctionTypes because CGBlocks.cpp constructs some dummy FunctionDecls with 'void' type.

DebugInfo: pass alignment value only if it was forced Preparation to implement DW_AT_alignment support: - We pass non-zero align value to DIBuilder only when alignment was forced - Modify tests to match this change Differential Revision: https://reviews.llvm.org/D24426 llvm-svn: 284679
