This implements a new flag -fcatch-undefined-behavior.  The flag turns
on additional runtime checks for:

  T a[I];

  a[i]    abort when i < 0 or i >= I.

Future stuff includes shifts by >= bitwidth amounts.

Make using '-fshort-enums' an error until it is actually implemented (changes the ABI, so it is dangerous to not error out if we don't support it).  Fixes <rdar://problem/7461006>.

Tests: Change substitution to automagically use 'clang -cc1' instead of 'clang-cc'. I still plan to eventually rewrite the tests to clarify the magic (I will probably actually rewrite them to %clang so it is more obvious this is a variable that gets substituted).
