Robert Griesemer c25bf0d959 cmd/compile/internal/types2: report types for mismatched call and return statements
Thanks to emmanuel@orijtech.com who wrote the initial version of
this change (CL 354490).

This change is following CL 354490 in idea but also contains various
simplifications, slightly improved printing of signature/type patterns,
adjustments for types2, and some fine-tuning of error positions.

Also adjusted several ERROR regexp patterns.

Fixes #48834.
Fixes #48835.
