Hi,
this patch makes cgrpahunit to output all thunks and aliases after the function,
not before. Outputting before leads to better code layout and we might omit
tailjump when thunk is just one, but it breaks one pass assembler and comdat

This is the easiest fix and I will play

Hi,
This patch allows to vectorize a subchain of interleaved loads in
basic block SLP (in loop vectorization this would be more complicated
because of loop peeling). This patch also swaps operands if necessary
(and possible) to make operations isomorphic.

here is a patch which fixes the regression in comment #2 of the PR in

- current_ns was not marked static.
- ASSOCIATE lists

Ok.
Factor the vector and chain output routines to remove boolean control
parameters. The functions pph_out_tree_vec_1 and pph_out_chain_1 split
their conditional parts of their implementation into their use cases,
calling each other as needed.
