[PATCH] D36764: The following functions and tests work fine for powerpc64, so enable them.

[Sterling Augustine via Phabricator via cfe-commits]

saugustine created this revision.

These functions were disabled for powerpc in the initial
checkin all the way back in 2009. The reasons why are lost to history,
but they work fine with modern clang and powerpc64.  I have no way
to test them on 32-bit systems, but will clean this up if the someone
finds a failure.
