[CFE] Use Fasta diagnostics in the constant evaluator.

The constant evaluator now generates all errors as Fasta diagnostic
messages. The ErrorReporter is simplified to just accept a diagnostic
message, or a notification that the constant evaluator encountered an
invalid expression (presumably put there due to an earlier error).

Also, the flow of control between the error reporter and the internal
abort exceptions is reversed, so the error reporter is now called as a
result of an abort exception being caught by the evaluate method.
