Ian Lance Taylor 85c2f96c1c syscall: fix creds_test to reliably close os.File 
Uncovered by Uros Bizjak.

Before this patch the test would close the file descriptor but
not the os.File.  When the os.File was GC'ed, the finalizer
would close the file descriptor again.  That would cause
problems if the same file descriptor were returned by a later
call to open in another test.

On my system:

--- FAIL: TestPassFD (0.04 seconds)

Teresa Johnson ca3f371f12 Avoid conservative behavior in REE by allowing removal of redundant extends when... 
Avoid conservative behavior in REE by allowing removal of redundant extends
when the def feeds another extend with a different mode. This works because
in merge_def_and_ext only calls combine_set_extension if the candidate for
removal has a wider mode than the def extend's mode, otherwise the def extend
mode is preserved. In combine_set_extension the def is modified to use the
wider candidate's mode.
