reference. CheckReferenceInit already inserts implicit casts to the necessary types. This fixes an assertion in CodeGen for some casts and brings a fix for PR5453 close, if I understand that bug correctly.
- Also, perform calculated implicit cast sequences if they're determined to work. This finally diagnoses static_cast to ambiguous or implicit bases and fixes two long-standing fixmes in the test case. For the C-style cast, this requires propagating the access check suppression pretty deep into other functions.
- Pass the expressions for TryStaticCast and TryStaticImplicitCast by reference. This should lead to a better AST being emitted for such casts, and also fixes a memory leak, because CheckReferenceInit and PerformImplicitConversion wrap the node passed to them. These wrappers were previously lost.

- Eliminates many calls to std::string.c_str()
- Fixes an invalid read in ReturnStackAddressChecker due to an unsafe call to
StringRef.data() which doesn't guarantee null-termination.

- This reimplements -verify as just another DiagnosticClient, which buffers the diagnostics and checks them when the source file is complete. There are some hacks to make this work, but they are all internal, and this exposes a better external interface.
- This also tweaks a few things:
o Errors are now just regular diagnostics.
o Frontend diagnostics are now caught (for example, errors in command line arguments), although there isn't yet a way to specify that they are expected. That would be nice though.
- Not yet used.

like a copy constructor to the overload set, just ignore it. This
ensures that we don't try to use such a constructor as a copy
constructor *without* triggering diagnostics at the point of
declaration.
Note that we *do* diagnose such copy constructors when explicitly
written by the user (e.g., as an explicit specialization).
