[power7-meissner] Add more builtins for vsx


This patch adds the rest of the builtins so that all of the VSX instructions
can be generated either through native code, or with builtins.  I also added
optimizations for V2DF/V2DI set, init, and extract builtins.  One non-VSX
power7 builtin (bpermd) was also added.  I switched the floating point compares
to use the VSX xscmpudp instruction instead of fcmpu.

I will be updating ibm-gcc-4_3-branch with the same patches shortly.
