Implement code generation for overloaded intrinsic functions. The basic difference is that "actual" argument types must be provided when constructing intrinsic names and types. Also, for recognition, only the prefix is examined. If it matches, the suffix is assumed to match. The suffix is checked by the Verifier, however. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35539 91177308-0d34-0410-b5e6-96231b3b80d8
