ReduceMin/Max operators return incorrect results with infinite values for HWY_EMU128 target

[yohanchatelain]

Hello,

I've noticed an issue with the ReduceMin operator when the input vector contains infinity values for the HWY_EMU128 target.

The issue seems to be caused by the following line of code:

highway/hwy/ops/emu128-inl.h

Line 2921 in fecd465

T min = HighestValue<T>();

as well as

highway/hwy/ops/emu128-inl.h

Line 2929 in fecd465

T max = LowestValue<T>();

Instead of using HighestValue/LowestValue, would it be more appropriate to initialize with +/-inf?

Absolutely! Thanks for pointing that out, fixing coming shortly.
