r303188 removed all the uses of aliases for EABI functions from compiler-rt, because some of them had mismatched calling conventions. Obviously, we can't use aliases for functions which don't have the same calling convention, but that's only an issue for floating-point functions with the hardfloat ABI. In other cases, the stubs increase size and reduce performance for no benefit. This patch adds back the aliases, with appropriate checks to make sure they're only used in cases where the calling convention matches. llvm-svn: 314851
