or1k: Update FPU to specify detect tininess before rounding

Browse source 
This was not defined in the spec and not consistent in the
implementation causing incosistent behavior.  After review we have
updated the CPU implementations and proposed the spec be updated to
specific that FPU tininess checks check for tininess before roudning.

Architecture change draft:

libgcc/ChangeLog:

	* config/or1k/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING):
	Change to 0.
