vect: Fix STMT_VINFO_DEF_TYPE check for odd/even widen mult [PR116348]
After fixing PR116142 some code started to trigger an ICE with -O3
-march=znver4. Per Richard Biener who actually made this fix:
"supportable_widening_operation fails at transform time - that's likely
because vectorizable_reduction "puns" defs to internal_def"
so the check should use STMT_VINFO_REDUC_DEF instead of checking if
STMT_VINFO_DEF_TYPE is vect_reduction_def.
gcc/ChangeLog:
PR tree-optimization/116348
* tree-vect-stmts.cc (supportable_widening_operation): Use
STMT_VINFO_REDUC_DEF (x) instead of
STMT_VINFO_DEF_TYPE (x) == vect_reduction_def.
gcc/testsuite/ChangeLog:
PR tree-optimization/116348
* gcc.c-torture/compile/pr116438.c: New test.
