gccrs: add two more tests to test try-catch (unwind) code generation
gcc/testsuite/ChangeLog:
* rust/compile/try-catch-unwind-old.rs: add a test to test the older
try intrinsics from plain old Rust to v1.78.0
* rust/compile/try-catch-unwind-new.rs: add a test to test the newer
catch_unwind instrinsics since Rust v1.78.0
