Hint that the current thread should pause.
In Burst compiled code this will map to platform specific
ways to hint that the current thread should be paused as
it is performing a calculation that would benefit from
not contending with other threads. Atomic operations in
tight loops (like spin-locks) can benefit from use of this
intrinsic.
- On x86 systems this maps to the pause instruction.
- On ARM systems this maps to the yield instruction.
Note that this is not an operating system level thread yield,
it only provides a hint to the CPU that the current thread can
afford to pause its execution temporarily.
