[PATCH] Fix new split-1.c testcase


The new split-1.c testcase fails on targets that do not support split
stack (like 32-bit PowerPC Linux).  This patch fixes it by only running
the testcase if split stack is supported.  It also adds the reorder
flag to the options, so that the test actually tests what it says it
tests.

Is this okay for trunk?

	Add -freorder-blocks-and-partition to options.
