nightly regression tests should run _MustFailCompile tests using x10.util.RunTestSuite

Description

The regression scripts should be changed to invoke RunTestSuite instead of the vanilla compilation command for all test cases that are MustFailCompile.

This will increase the odds that the test case is failing to compile for the right reason.
