test_peg_generator and test_freeze require cpu

The test_peg_generator and test_tools.test_freeze tests now require
the 'cpu' resource. Skip these tests unless the 'cpu' resource is
enabled (it is disabled by default).

These tests are no longer skipped if Python is built with ASAN or
MSAN sanitizer.
