tree-optimization/111846 - put simd-clone-info into SLP tree
The following avoids bogously re-using the simd-clone-info we
currently hang off stmt_info from two different SLP contexts where
a different number of lanes should have chosen a different best
simdclone.
PR tree-optimization/111846
* tree-vectorizer.h (_slp_tree::simd_clone_info): Add.
(SLP_TREE_SIMD_CLONE_INFO): New.
* tree-vect-slp.cc (_slp_tree::_slp_tree): Initialize
SLP_TREE_SIMD_CLONE_INFO.
(_slp_tree::~_slp_tree): Release it.
* tree-vect-stmts.cc (vectorizable_simd_clone_call): Use
SLP_TREE_SIMD_CLONE_INFO or STMT_VINFO_SIMD_CLONE_INFO
dependent on if we're doing SLP.
* gcc.dg/vect/pr111846.c: New testcase.
