test: re-enable AsmCheck tests for types2-based frontends
run.go has logic for being able to run tests with various -G flags,
but not all test types (in particular, "asmcheck" tests) support
configuring non-default -G levels. The intention was that these tests
would continue running in the default mode (at the time -G=0), but at
some point it seems like we accidentally disabled them all
together (if it ever worked correctly in the first place).
Fixes #48247.
