[clang] Introduce elementwise ctlz/cttz builtins (#131995)
These builtins are modeled on the clzg/ctzg builtins, which accept an
optional second argument. This second argument is returned if the first
argument is 0. These builtins unconditionally exhibit zero-is-undef
behaviour, regardless of target preference for the other ctz/clz
builtins. The builtins have constexpr support.
Fixes #154113
