d954638f02 Implement runtime checks for undefined behavior. WIP.
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.

eadc7c3537 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>.

a1b02a2380 Move LLVM backend options to explicit clang-cc / clang -cc1 options, which we then manually pass to the command line library; eventually the latter grossness should be fixed by a real API when creating the target machine.

e13ada6a3b Add clang -mcpu=native support, patch by Roman Divacky, varioustweaks by me.
- We still need support for detecting the target features, since the name
   doesn't actually do a good job of decribing what the CPU supports (for LLVM).
