tree-opt: Fix bootstrap failure in tree-ssa-forwprop.c some more PR90838
2020-01-13 Jakub Jelinek <jakub@redhat.com>
PR tree-optimization/90838
* tree-ssa-forwprop.c (simplify_count_trailing_zeroes): Use
SCALAR_INT_TYPE_MODE directly in CTZ_DEFINED_VALUE_AT_ZERO macro
argument rather than to initialize temporary for targets that
don't use the mode argument at all. Initialize ctzval to avoid
warning at -O0.
