vect: Fix vect_reduction_def check for odd/even widen mult [PR116142]
The check was implemented incorrectly, so vec_widen_smult_{even,odd}_M
was never used. This is not good for targets with native even/odd
widening multiplication but not lo/hi multiplication.
The fix is actually developed by Richard Biener.
gcc/ChangeLog:
PR tree-optimization/116142
* tree-vect-stmts.cc (supportable_widening_operation): Remove an
redundant and incorrect vect_reduction_def check, and fix the
operand of another vect_reduction_def check.
gcc/testsuite/ChangeLog:
PR tree-optimization/116142
* gcc.target/i386/pr116142.c: New test.
