cmd/compile: fix any in -G=0 mode

Browse Source 
Fixes go test -gcflags=all=-G=0 -short std,
except for the packages with generics in their tests
(constraints, encoding/xml), and except for the
go/internal/gcimporter and go/types tests,
because the compiler does not preserve any
in its -G=0 export information.
(That's probably acceptable for now.)

Fixes cd test/; GO_BUILDER_NAME=longtest go run run.go
completely, which should fix the longtest builder.

Fixes #50159.
