Issue Description:

Currently, Swift has -debug-crash-immediately and -debug-crash-after-parse and -debug-assert-after-parse. The problem is twofold:

1) -debug-assert-after-parse understands the old hat meaning of "-parse" which used to mean "parse and type check". Now that the compiler understands these are distinct actions, this flag is misnamed.

2) The more useful distinction is crashing immediately versus crashing after a particular phase.

We should generalize -debug-assert and -debug-crash to mean "assert after the current frontend action finishes" or "crash after the current frontend action finishes" respectively. -debug-crash-immediately should still be retained because there needs to be a way to crash argument parsing.
