testsuite: Move no_lint to the top level, tweak hie002

- We don't want to benchmark linting so disable lints in hie002 perf
  test

- Move no_lint to the top-level to be able to use it in tests other than
  those in `testsuite/tests/perf/compiler`.

- Filter out -dstg-lint in no_lint.

- hie002 allocation numbers on 32-bit are unstable, so skip it on 32-bit

Metric Decrease:
