rs6000: Handle some recent MMA builtin changes

Peter Bergner recently added two new builtins __builtin_vsx_lxvp and
__builtin_vsx_stxvp.  These happened to break a pattern in MMA builtins that
I had been using to automate gimple folding of MMA builtins.  Previously,
every MMA function that could be folded had an associated internal function
that it was folded into.  The LXVP/STXVP builtins are just folded directly
into memory operations.

Instead of relying on this pattern, this patch adds a new attribute to
builtins called "mmaint," which is set for all MMA builtins that have an
associated internal builtin.  The naming convention that adds _INTERNAL to
the builtin index name remains.

The rest of the patch is just duplicating Peter's patch, using the new
builtin infrastructure.
