RandomX (Golang Implementation)

Fork from git.dero.io/DERO_Foundation/RandomX. Also related, their Analysis of RandomX writeup.

Original code failed RandomX testcases and was implemented using big.Float.

This package implements RandomX without CGO, using only Golang code, pure float64 ops and two small assembly sections to implement CFROUND modes, with optional soft float implementation.

All test cases pass properly.

JIT is supported on a few platforms but can be hard-disabled via the disable_jit build flag, or at runtime.

A pure Golang implementation can be used on platforms without hard float support or via the purego build flag manually.

Any platform with no hard float support (soft float using softfloat64) will be vastly slow.

Native hard float can be added with supporting rounding mode under asm.
