jdk8u-dev MacOS 10.15+ build environment?

[Taylor, Ben]

Hi,

In parallel with Simon's work [1], we've created a patch set against 8u282 that supports this through a combination of Simon's patches to the build system and a backport of JDK-8182299 [2] and associated follow-up patches. 

The patch set has been uploaded to [3], and includes a markdown document [4] describing the patches and how they were built and applied.

Thanks,

    The rules about backports to new environments tend to be more
    relaxed than general enhancements. We want JDK 8u to continue
    to be relevant for as long as it is supported; that's why we
    allowed AArch64 support to be imported into 8u. So, let's get
    this done.
