The effect and motivation is for the test to be selected when doing
'go test cmd' and not when doing 'go test std' since it's primarily
about testing the Go compiler and linker. Other than that, it's run
by all.bash and 'go test std cmd' as before.
For #56844.
Fixes#60059.

As motivated on the issue, we want to move the functionality of the
run.go program to happen via a normal go test. Each .go test case in
the GOROOT/test directory gets a subtest, and cmd/go's support for
parallel test execution replaces run.go's own implementation thereof.
The goal of this change is to have fairly minimal and readable diff
while making an atomic changeover. The working directory is modified
during the test execution to be GOROOT/test as it was with run.go,
and most of the test struct and its run method are kept unchanged.
The next CL in the stack applies further simplifications and cleanups
that become viable.
There's no noticeable difference in test execution time: it takes around
60-80 seconds both before and after on my machine. Test caching, which
the previous runner lacked, can shorten the time significantly.
For #37486.
Fixes#56844.

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.

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

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
