unique.Make always copies strings passed into it, so it's safe to not
copy byte slices converted to strings either. Handle this just like map
accesses with string(b) as keys.
This CL only handles unique.Make(string(b)), not nested cases like
unique.Make([2]string{string(b1), string(b2)}); this could be done in a
followup CL but the map lookup code in walk is sufficiently different
than the call handling code that I didn't attempt it. (SSA is much
easier).
Fixes#71926

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.
