From-SVN: r237184

This patch adds support for the missing versions of the vec_mul altivec
builtins from the Power Architecture 64-Bit ELF V2 ABI OpenPOWER ABI for
Linux Supplement (16 July 2015 Version 1.1). There are many of the builtins
that are missing and this is part of a series of patches to add them.

There aren't instructions for the {un}signed char, {un}signed short, and
{un}signed int versions of vec_mul so the output code is built from other
built-ins and operations that do have instructions.

The new test case is an executable test which verifies that the generated
code produces expected values. C macros were used so that the same
test case could be used for all the various supported types.

Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64-unknown-linux-gnu with no regressions. Is this ok for trunk?
