Robert Griesemer 7a1aa7dfaf [dev.typeparams] test: adjust more test cases to match compiler -G output
With this CL, the first ~500 errorcheck tests pass when running

go run run.go -v -G

in the $GOROOT/test directory (the log output includes a few dozen
tests that are currently skipped).

Alberto Donizetti 1737aef270 cmd/compile: more error position tests for the typechecker
This change adds line position tests for several yyerror calls in the
typechecker that are currently not tested in any way.

Untested yyerror calls were found by replacing them with

  yerrorl(src.NoXPos, ...)

(thus destroying position information in the error), and then running
the test suite. No failures means no test coverage for the relevant
yyerror call.

For #19683
