This CL renames blank functions in the test/ directory so that they
don't rely on the compiler doing anything more than typechecking them.
In particular, I ran this search to find files that used blank
functions and methods:
$ git grep -l '^func.*\b_(' | xargs grep -n '^' | grep '\.go:1:' | grep -v '// errorcheck$'
I then skipped updating a few files:
* blank.go
* fixedbugs/issue11699.go
* fixedbugs/issue29870.go
These tests specifically check that blank functions/methods work.
* interface/fail.go
Not sure the motivation for the blank method here, but it's empty
anyway.
* typeparam/tparam1.go
Type-checking test, but uses "-G" (to use types2 instead of typecheck).
Updates #47446.

Historically, gc optimistically parsed the left-hand side of
assignments as expressions. Later, if it discovered a ":=" assignment,
it rewrote the parsed expressions as declarations.
This failed in the presence of dot imports though, because we lost
information about whether an imported object was named via a bare
identifier "Foo" or a normal qualified "pkg.Foo".
This CL fixes the issue by specially noding the left-hand side of ":="
assignments.
Fixes#22076.
