[PATCH, go]: Skip some go tests

[Uros Bizjak]

Hello!

Attached patch skip some go tests to avoid testsuite failures:

- peano.go tests recursive call. The test fails on targets that don't
support -fsplit-stack (Centos 5.3, alpha)
- rotate[0123]-out.go take too long to compile. The test should be
skipped for the same reason as rotate.go:

        # This test produces a temporary file that takes too long
        # to compile--5 minutes on my laptop without optimization.
        # When compiling without optimization it tests nothing
        # useful, since the point of the test is to see whether
        # the compiler generates rotate instructions.

There are two remaining warnings:

go.test/test/nilcheck.go: unrecognized test line: // errorcheck -0 -N -d=nil
go.test/test/nilptr3.go: unrecognized test line: // errorcheck -0 -d=nil

(The patch doesn't address these warnings).

    * go.test/go-test.exp (go-gc-tests): Don't run peano.go on systems
    which don't support -fsplit-stack.  Skip rotate[0123]-out.go.

Patch was tested on alpha-linux-gnu, where it fixes all but
recovery.go failure; the latter due to unimplemented feature on alpha
target.

OK for mainline?

Uros.
