Adhemerval Zanella 822bb11278 math: Order signed zeros in f{max,min}mag{f,l,f128} 
The functions are documented to behave like fmax/fmin when the
arguments have the same absolute value.

Checked on x86_64-linux-gnu, aarch64-linux-gnu, i686-linux-gnu,
arm-linux-gnueabihf, powerpc64le-linux-gnu,
riscv64-linux-gnu-rv64imafdc-lp64d, and loongarch64-linux-gnuf64.
