Matt Arsenault 505c550e4c DAG: Assert fcmp uno runtime calls are boolean values (#142898) ...

This saves 2 instructions in the ARM soft float case for fcmp ueq.

This code is written in an confusingly overly general way. The point
of getCmpLibcallCC is to express that the compiler-rt implementations
of the FP compares are different aliases around functions which may
return -1 in some cases. This does not apply to the call for unordered,
which returns a normal boolean.

Also stop overriding the default value for the unordered compare for ARM.
This was setting it to the same value as the default, which is now assumed.
