bmeurer ba092fb09a [turbofan] Change Float64Max/Float64Min to JavaScript semantics. 
So far we don't have a useful way to inline Math.max or Math.min in
TurboFan optimized code. This adds new operators NumberMax and NumberMin
and changes the Float64Max/Float64Min operators to have JavaScript
semantics instead of the C++ semantics that it had previously.

This also removes support for recognizing the tenary case in the
CommonOperatorReducer, since that doesn't seem to have any positive
impact (and actually doesn't show up in regular JavaScript, where
people use Math.max/Math.min instead).

Drive-by-fix: Also nuke the unused Float32Max/Float32Min operators.
