Robert Griesemer c65a2781be cmd/compile: better handling of incorrect type switches
Don't report errors if we don't have a correct type switch
guard; instead ignore it and leave it to the type-checker
to report the error. This leads to better error messages
concentrating on the type switch guard rather than errors
around (confusing) syntactic details.

Also clean up some code setting up AssertExpr (they never
have a nil Type field) and remove some incorrect TODOs.

Fixes #24470.
