A Method to Satisfy `strictfp' Semantics

This technique was developed and proposed by Roger A. Golliver (Intel).
A combination of store-reload and scaling techniques.
Java Grande Forum Numerics Working Group (JGNWG) recommends this technique because of the low penalty of it.

Golliver's technique achieves complete compliance with what the language spec. prescribes.
cf. The store-reload cannot prevent the double rounding by itself.

The technique introduces small 2- or 4-fold penalty.
cf. Emulation bit by bit.
