During combine GCC tries to merge CMP (with zero) and AND into a TST. However,

While answering a user question on the equivalence of
-ftree-loop-vectorize + -ftree-slp-vectorize and -ftree-vectorize I
spotted one case which broke the equivalence. pass_ch::process_loop_p
was guarded on flag_tree_vectorize, meaning you would get it for
-ftree-vectorize, but not for -ftree-loop-vectorize/-ftree-slp-vectorize.

This patch fixes that, getting rid of the only use of flag_tree_vectorize
in the code base.

The little-endian VSX code uses rotates to swap the two 64-bit halves of
128-bit scalar modes.  This is fine for TImode and V1TImode, but it
isn't really valid to use RTL rotates on floating-point modes like
KFmode and TFmode, and doing that triggered an assert added by the
SVE series.  This patch uses bit-casts to V1TImode instead.
