This fixes the type of stmt_vec_info_vec and avoids the pointless
creation of a loop_vec_info for the inner loop when doing outer loop
vectorization.
Bootstrapped / tested on x86_64-unknown-linux-gnu, applied.

The following makes us create less useless statements (as can be seen
from the needed change to recip-vec-sqrtf-avx.c where we now fully
unroll one of the loops).
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

This splits out load permutation computation from SLP tree building.
It also removes the broken support for swapping mismatched operands.
If it ever triggers we'll ICE later because:
case vect_internal_def:
! if (different_types)
! {
! oprnd0_info = (*opr
This splits discovering of a SLP opportunity (vect_build_slp_tree)
and calculating the cost of a SLP instance (now vect_analyze_slp_cost).
The immediate need for me is to support handling of mismatches
in the SLP tree due to commutative operand order mismatch, one more
cleanup patch for this reaso
The following is a collection of TLC sitting in my local tree,
mostly resulting in less obscure IL after vectorization.
Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

* tree-vect-loop-manip.c (vect_create_cond_for_alias_checks):
I noticed a write-only bitmap and some odd CFG hooks initializing code.
Removed as follows.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Remove set-only bitm
