Here, we don’t believe the KMP_ARCH_AARCH64 is correct because those dispatch routines are for 32-bit architectures.  It should be using the 64 bit versions (in the #else part).

Does anyone have a patch for AArch64 support? Either experimental, complete or notes/suggestions.

So here's a 1st draft for review - I don't expect it to be clean on the 1st pass, but getting some review would be really appreciated.

btw - Is anyone testing this on ARM or PPC64 regularly?
