Make CalculateParameterAndLinkageAreaSize() Darwin-specific. Remove SVR4 specific code from LowerCALL_Darwin() and LowerFORMAL_ARGUMENTS_Darwin(). Rename MachoABI to DarwinABI for consistency. Rename ELF ABI to SVR4 ABI for consistency. Factor out common call return lowering between the Darwin and SVR4 ABI. Factor out common call lowering between the Darwin and SVR4 ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74766 91177308-0d34-0410-b5e6-96231b3b80d8
