tree-optimization/121592 - failed reduction SLP discovery
The testcase in the PR shows that when we have a reduction chain
with a wrapped conversion we fail to properly fall back to a
regular reduction, resulting in wrong-code. The following fixes
this by failing discovery. The testcase has other issues, so
I'm not including it here.
PR tree-optimization/121592
* tree-vect-slp.cc (vect_analyze_slp): When SLP reduction chain
discovery fails, fail overall when the tail of the chain
isn't also the entry for the non-SLP reduction.
