Connor Wakamo 9747d87ff6 [frontend] Added a handful of options to force the frontend to assert or crash. ...

Added -debug-assert-immediately and -debug-crash-immediately, which cause an
llvm_unreachable or LLVM_BUILTIN_TRAP to execute during argument parsing.

Added -debug-assert-after-parse and -debug-crash-after-parse, which cause an
llvm_unreachable or LLVM_BUILTIN_TRAP to execute after calling
CompilerInstance::performParse().

This fixes <rdar://problem/16013025>.
