The new cortex-m schedule in rL360768 helps performance, but can increase the

the existing DAG scheduler with the RegPressure scheduling preference (at least

[X86] Use OR32mi8Locked instead of LOCK_OR32mi8 in emitLockedStackOp.
They encode the same way, but OR32mi8Locked sets hasUnmodeledSideEffects set
which should be stronger than the mayLoad/mayStore on LOCK_OR32mi8. I think
this makes sense since we are using it as a fence.
This also seems to hide the operation from the speculative load hardening pass
so I've reverted r360511.

The 3-field form was introduced by D3499 in 2014 and the legacy 2-field

For the textual format, this patch migrates the existing 2-field form to
use the 3-field form and deletes the compatibility code.
test/Verifier/global-ctors-2.ll checks we have a friendly error message.

The code is currently using the ambiguous instruction
"sub sp, sp, w9, lsl #4". The ARM reference manual says this isn't

It doesn't matter which instruction we use here, since the high
bits of the operand are zero anyway, so I arbitrarily choose uxtw, to
preserve the register name.
