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.
