Cuong Manh Le 286a79658e cmd/compile: fix missing walk for OAS2RECV node

When channel receive operator is used in the context that requires
conversion to destination type, there's an implicit conversion operator
inserted by typecheck. This typecheck-ed node is un-walked, then passing
to the backend as-is, causing the ICE.

Fixes #78313

README.md

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

../bin/go test cmd/internal/testdir

To run just tests from specified files in this directory, execute:

../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.go|...)'

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

it is most naturally expressed using the test runner; or
it is also applicable to gccgo and other Go tool chains.
