Keith Randall 6b165577fe cmd/compile: remove memequal call from string compares in more cases
Add more rules to ensure that order doesn't matter.

Add memequal 0 rule.

Try to use a constant argument to memequal when one is available.

Fixes #59684

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 internal/testdir

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

../bin/go test 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.
