AtomicOps: Avoid constrained unpredictable case in TelemetrySetValue()
...
STLXR cannot use the same register as both the status register and the
value register, otherwise it's architecturally unpredictable
behavior.
Only applies to hardware without FEAT_LSE, so this only meaningfully
affects hardware using the v8.0 spec, since FEAT_LSE becomes mandatory
in v8.1 and newer.

ShouldClose was never being set in the event we opened a regular file.
The only time it was set (to false) is when it's used to encapsulate
stderr and stdout.
So anything opened by a File instance was essentially held open.

Same functional behavior, just makes it visually match the store size
below. Technically also avoids delegating off to the 64-bit element
path if a 128-bit constant zero is already loaded.

This used to be used for the intrusively allocated `LiveVMARegion` but
that is all handled internally to the object now, making this
unnecessary. It was always receiving zero and doing nothing so just
remove it.

Lets us shave off an instruction and also avoid using a temporary
register in some cases. We can also tweak our worst case that requires a
predicate to eliminate the temporary as well.
We can also expand our cmpps cases, so that we can reflect the
BSL2N usages in instcountci.

Common/BitSet: Amend byte size retrieval

This needs to divide by 8 to get a proper byte size for all type sizes.
The only usage of this is currently a uint64_t, so it worked by
coincidence, since sizeof(uint64_t) == 8.

Because our bitset type is uint64_t, then that means Memory + ManagedSize
is more like: Memory + (ManagedSize * 8), which is way larger of a base
than we need.

This just means the end of the file is being used as the base offset.
Also note that according to the documentation for SetFilePositionEx,
that setting the position beyond the current file size is not considered
an error as far as the API is concerned.
