Support Java Behaviour w.r.t Math.max and Math.min for Floating Points

[matthewhall2]

• Enables inlining of Math.max/Math.min functions for floats and doubles
• Implements Java standard found while testing
  • +0 compares as strictly greater than -0
  • if the first arg is a NaN, returns the corresponding quiet NaN, same for if only the second arg is a NaN

This is the same as #20185 with the functional test change removed

The original change was causing crashes on z/OS.

Setting as draft until the z/OS problems are resolved.
