This commit introduces the `ctlz` and `ctlz_nonzero` intrinsics for counting leading zeros in integer types. The implementation includes handlers for both intrinsics, which validate input types and utilize GCC built-ins for the actual computation. Addresses: Rust-GCC#658 gcc/rust/ChangeLog: * backend/rust-compile-intrinsic.cc: Register ctlz and ctlz_nonzero intrinsics. * backend/rust-intrinsic-handlers.cc (ctlz_handler): Implement ctlz_handler. (ctlz_nonzero_handler): Implement ctlz_nonzero_handler. * backend/rust-intrinsic-handlers.h (ctlz_handler): Add decl for ctlz_handler. (ctlz_nonzero_handler): Add decl for ctlz_nonzero_handler. * util/rust-intrinsic-values.h: map ctlz_nonzero to its name. gcc/testsuite/ChangeLog: * rust/compile/ctlz.rs: New test. * rust/compile/ctlz_nonzero.rs: New test. * rust/execute/torture/ctlz.rs: New test. * rust/execute/torture/ctlz_nonzero.rs: New test.
