I updated everything to the latest Unity Editor. Also realized I had the wrong shaders on my hairs, those are fixed and the hairs look MUCH better!

Burst Intrinsics Common class
The Unity.Burst.Intrinsics.Common intrinsics are for functionality shared across the hardware targets that Burst supports.
Pause
Unity.Burst.Intrinsics.Common.Pause is an intrinsic that requests that the CPU pause the current thread. It maps to pause on x86, and yield on ARM.
Use it to stop spin locks over contending on an atomic access, which reduces contention and power on that section of code.
Prefetch
The Unity.Burst.Intrinsics.Common.Prefetch is an experimental intrinsic that provides a hint that Burst should prefetch the memory location into the cache.
Because the intrinsic is experimental, you must use the UNITY_BURST_EXPERIMENTAL_PREFETCH_INTRINSIC preprocessor define to get access to it.
umul128
Use the Unity.Burst.Intrinsics.Common.umul128 intrinsic to access 128-bit unsigned multiplication. These multiplies are useful for hashing functions. It maps 1:1 with hardware instructions on x86 and ARM targets.
InterlockedAnd & InterlockedOr
The Unity.Burst.Intrinsics.Common.InterlockedAnd and Unity.Burst.Intrinsics.Common.InterlockedOr are experimental intrinsics that provides atomic and/or operations on int, uint, long, and ulong types.
Because these intrinsics are experimental, you must use the UNITY_BURST_EXPERIMENTAL_ATOMIC_INTRINSICS preprocessor define to get access to them.
