  [PowerPC] Remove vnot_ppc and replace with the standard vnot.

immAllOnesV has special support for looking through bitcasts
automatically so isel patterns don't need to explicitly look
for the bitconvert.

  -----------
  [Mips] Cleanup isel patterns to use 'vnot' instead of (xor X, immAllOnesV). NFCI

A couple patterns used bitconvert on the immAllOnesV, but
the isel matching uses ISD::isBuildVectorAllOnes which
is able to look through bitcasts. So isel patterns don't need
to do it explicitly.
