Problems building foreign-memaccess+abi on MacOS

[leerho]

Success!

I was already using clang 9.0.0, but I had renamed the root directory of
clang to "9.0.0" and installed it in a parallel directory to the
"clang/12.0.0" in the Xcode tree.

This time I downloaded 9.0.1, kept the root directory the same:
"clang+llvm-9.0.1-x86_64-apple-darwin" and saved it in my local account.

It completes the configure phase just fine.  I installed the JTreg and am
able to run tests,
but I do get a few FMA failures due to "obsolete or changed code".  I
presume this is because the code is still volatile.

Is there a way to run just the FMA tests without testing the entire JVM?

Thanks!

Lee.
