Add support for XFAILing valgrind runs with memory leak checking independently

of runs without leak checking.  We add -vg to the triple for non-checked runs,
or -vg_leak for checked runs.  Also use this to XFAIL the TableGen tests, since
tablegen leaks like a sieve.  This includes some valgrindArgs refactoring.
