Address @rsmith & @erichkeane [IRC] review notes:

- https://reviews.llvm.org/D49838 - [AST] Sink 'part of explicit cast' down into ImplicitCastExpr
- https://reviews.llvm.org/D49844 - [AST] Add a isActuallyImplicitCast() helper to the CastExpr class.
- Drop no longer needed `CastExprStackGuard`, `ScalarExprEmitter::IsTopCastPartOfExplictCast()`, just use `CastExpr::isActuallyImplicitCast()` directly.

This should be a NFC change, there should not be any functionality change because of this.
