[PATCH] D79755: Implement constexpr BinaryOperator for vector types

[Erich Keane via Phabricator via cfe-commits]

These operations do member-wise versions of the all of the listed
operations.  This patch implements all of the binaryoperators for these
types. Note that the test is required to use codegen as I could not come
up with a good way to validate the values without the array-subscript
operator implemented (which is likely a much more involved change).

This is not full constexpr support for these types, but should at least 
support a large number of uses.
