all: avoid use of cmd/compile -G flag in tests The next CL will remove the -G flag, effectively hard-coding it to its current default (-G=3).

cmd/compile: don't crash while reporting invalid alias cycle Add a missing nil check in the formatting code for expression nodes. Matches the nil checks in the same code. Fixes #48301.

go/types, types2: more concise error messages for cycle errors If a cycle has length 1, don't enumerate the single cycle entry; instead just mention "refers to itself". For instance, for an invalid recursive type T we now report: invalid recursive type: T refers to itself instead of: invalid recursive type T T refers to T Adjust tests to check for the different error messages.
