[jdk17u-dev] RFR: 8322985: [BACKOUT] 8318562: Computational test more than 2x slower when AVX instructions are used

[Aleksey Shipilev]

This reverts the patch that caused recently identified regression. Luckily, we have it only in 17.0.11, which gives us a normal opportunity to revert it.

The complication is that mainline patch is not applying cleanly, because JDK 17u backport is contextually different. So I `git revert`-ed the jdk17u-dev commit instead: https://github.com/openjdk/jdk17u-dev/commit/9a104e08f79fecabf5de2e0ece914260319d2f28. But that makes the backport formally unclean.

Additional testing:
