Stafford Horne b77f6d2fa8 or1k: Support for softfloat to emulate hw exceptions 
This allows the openrisc softfloat implementation to set exceptions.
This also sets the correct tininess after rounding value to be
consistent with hardware and simulator implementations.

libgcc/ChangeLog:

	* config/or1k/sfp-machine.h (FP_RND_NEAREST, FP_RND_ZERO,
	FP_RND_PINF, FP_RND_MINF, FP_RND_MASK, FP_EX_OVERFLOW,
	FP_EX_UNDERFLOW, FP_EX_INEXACT, FP_EX_INVALID, FP_EX_DIVZERO,
	FP_EX_ALL): New constant macros.
	(_FP_DECL_EX, FP_ROUNDMODE, FP_INIT_ROUNDMODE,
	FP_HANDLE_EXCEPTIONS): New macros.
	(_FP_TININESS_AFTER_ROUNDING): Change to 1.
