tree-optimization/120032 - matching of table based CLZ
The following adds the ability to match a table based CLZ implementation
similar as to how we can do for CTZ. I'm re-using the workers for
matching up array and string tables by using a lambda and templates
and kept the transform step for CLZ/CTZ inter-mangled.
PR tree-optimization/120032
* match.pd (clz_table_index): New match.
* tree-ssa-forwprop.cc (check_table_array): Rename from
check_ctz_array. Split out actual verification to a functor.
(check_table_string): Rename from check_ctz_string and likewise.
(check_table): Rename from check_ctz_table and adjust.
(gimple_clz_table_index): Declare.
(simplify_count_zeroes): Rename from simplify_count_trailing_zeroes.
Extend to cover CLZ.
(pass_forwprop::execute): Adjust.
* gcc.target/i386/pr120032-1.c: New testcase.
* gcc.target/i386/pr120032-2.c: Likewise.
