MIPS: [turbofan] Introduce optional Float64Min and Float64Max machine operators.

Browse Source 
Port 99f8d57f3c

Original commit message:
Basically recognize certain x < y ? x : y constructs and turn that into
Float64Min/Float64Max operations, if the target machine supports that.
On x86 we lower to (v)minsd/(v)maxsd.
