Xref #6499 where a64 scatter/gather are going to marked as predicated. This issue covers doing the same thing for x86. This should include all SIMD operations with masks. We may...

Just like we're adding canned kernel syscall sequences in #6495, we'd like to insert some roughly-representative kernel context switch sequence as well. Like the syscalls this will probably be fed...

Xref #4381 This covers adding `-syntax_aarch64` and `DR_DISASM_AARCH64` support for disassembly in standard style for AArch64. (Using `DR_DISASM_ARM` results in no operands being printed at all: #4381).

This happened 3x in a row (else it would have passed) -- yet I don't think we've ever seen this before. This test passed in other runs of the same...

Splitting from #2145 as it does not look like this is easily solved. I can repro the common.floatpc_xl8all failure seen on Appveyor on my local win10 and win8.1 VM's every...
