[TargetLowering][ARM][Mips][WebAssembly] Remove the ordered FP compare
from RunttimeLibcalls.def and all associated usages
Summary: This always just used the same libcall as unordered, but the
comparison predicate was different. This change appears to have been
made when targets were given the ability to override the predicates.
Before that they were hardcoded into the type legalizer. At that time we
never inverted predicates and we handled ugt/ult/uge/ule compares by
emitting an unordered check ORed with a ogt/olt/oge/ole checks. So only
ordered needed an inverted predicate. Later ugt/ult/uge/ule were
optimized to only call a single libcall and invert the compare.
This patch removes the ordered entries and just uses the inverting logic
that is now present. This removes some odd things in both the Mips and
WebAssembly code.
