sfp-exceptions.c (__sfp_handle_exceptions): Handle FP_EX_DENORM.

* config/i386/sfp-exceptions.c (__sfp_handle_exceptions): Handle
FP_EX_DENORM.  Store result to volatile location after SSE division
to close interrupt window.  Remove unneeded fwait after x87
division since interrupt window will be closed by emitted fstp.
