This adds the long overdue implementations of these functions that have been part of the ABI document and are now part of the "Power Vector Intrinsic Programming Reference" (PVIPR).

The approach is to add new builtins and to emit code with the `fast` flag regardless of whether fastmath was specified on the command line.
