  [SCEV] PtrToInt on non-integral pointers is allowed

As per (committed without review) @reames's rGac81cb7e6dde9b0890ee1780eae94ab96743569b change,
we are now allowed to produce `ptrtoint` for non-integral pointers.
This will unblock further unbreaking of SCEV regarding int-vs-pointer type confusion.

  [NFC][X86] lowerVECTOR_SHUFFLE(): drop FIXME about widening to i128 (YMM half) element type

As per the discussion in D103818, so far, this does not appear to be worthwhile.
