[PATCH, ARM] Define REVERSE_CONDITION

[Richard Earnshaw]

Now that I think I've identified all the cases in the compiler where we 
might be calling reverse_condition with a floating-point comparison, we 
can now do the following without causing regressions when generating 
cond_exec instructions from floating-point comparisons.  This also fixes 
an ICE seen in CSiBE when building on arm-linux -Os.

Bootstrapped on arm-linux, no regressions.

	* arm.h (REVERSE_CONDITION): Define.
	(REVERSIBLE_CC_MODE): All comparisons are now reversible.
