cmd/compile: confusing internal error when importing different packages with same name from different paths #25635

This is a follow-up on #25568: It is possible to get an internal compiler error when invoking the compiler with plausible but incorrect -I arguments leading to selection of different but identically named packages ("io" in this case). To reproduce:

  1. cd $GOROOT/test
  2. go tool compile fixedbugs/bug345.dir/io.go
  3. go tool compile -I . fixedbugs/bug345.dir/main.go
fixedbugs/bug345.dir/main.go:10:2: internal compiler error: conflicting package heights 4 and 0 for path "io"

The issue here is an incorrect argument for -I. The following invocation:

go tool compile -I $HOME/test/fixedbugs/bug345.dir fixedbugs/bug345.dir/main.go

works as expected.

The internal error is confusing. We should be able to provide a better error message.
