Russ Cox 801a9d9a0c test/codegen: mention in README that tests only run on Linux without -all_codegen 
This took me a while to figure out. The relevant code is in
test/run.go (note the "linux" hard-coded strings):

	var arch, subarch, os string
	switch {
	case archspec[2] != "": // 3 components: "linux/386/sse2"
		os, arch, subarch = archspec[0], archspec[1][1:], archspec[2][1:]
	case archspec[1] != "": // 2 components: "386/sse2"
		os, arch, subarch = "linux", archspec[0], archspec[1][1:]
	default: // 1 component: "386"
		os, arch, subarch = "linux", archspec[0], ""
		if arch == "wasm" {
			os = "js"
		}
	}

Alberto Donizetti c2facbe937 Revert "test/codegen: document -all_codegen option in README" 
This reverts CL 192101.

Reason for revert: The same paragraph was added 2 weeks ago
(look a few lines above)

Cherry Zhang d9b8ffa51c test/codegen: document -all_codegen option in README 
It is useful to know about the -all_codegen option for running
codegen tests for all platforms. I was puzzling that some codegen
test was not failing on my local machine or on trybot, until I
found this option.

Alberto Donizetti e6d2544d20 test/codegen: mention -all_codegen in the README 
For performance reasons (avoiding costly cross-compilations) CL 177577
changed the codegen test harness to only run the tests for the
machine's GOARCH by default.

This change updates the codegen README accordingly, explaining what
all.bash does run by default and how to perform the tests for all
architectures.

Fixes #33924

Giovanni Bajo 284ba47b49 test: run codegen tests on all supported architecture variants 
This CL makes the codegen testsuite automatically test all
architecture variants for architecture specified in tests. For
instance, if a test file specifies a "arm" test, it will be
automatically run on all GOARM variants (5,6,7), to increase
the coverage.

The CL also introduces a syntax to specify only a specific
variant (eg: "arm/7") in case the test makes sense only there.
The same syntax also allows to specify the operating system
in case it matters (eg: "plan9/386/sse2").

Fixes #24658
