[patch] [spu] Disable inaccurate divdf3 expander in spu.md

[Victor Kaplansky]

This patch disables inaccurate divdf3 expander on SPU and adds a new
testcase which demonstrate the problem.

This patch will be following by another one which will add a fast
implementation of divdf3 to libgcc.

OK for mainline after regression testing?
