target-ppc: Add VSX xmax/xmin Instructions
This patch adds the VSX floating point maximum and minimum
instructions:
- xsmaxdp, xvmaxdp, xvmaxsp
- xsmindp, xvmindp, xvminsp
Because of the Power ISA definitions of maximum and minimum
on various boundary cases, the standard softfloat comparison
routines (e.g. float64_lt) do not work as well as one might
think. Therefore specific routines for comparing 64 and 32
bit floating point numbers are implemented in the PowerPC
helper code.
