...
This takes an f80 as input and returns an f32. A copy-paste error had
this truncating the input float if !TMP_ABIARGS.

OpcodeDispatcher: Only flush MMX registers on MMX -> x87 transitions
...
Flushing other regs is not necessary, and breaks any ConvertNZCVToX87 use
which relies previously saved NZCV values as the flag-setting NZCV op after
the save could trigger a flush of NZCV.

Dispatcher: Move the EC entrypoint check prior to the L1 lookup
...
Profiling shows this is by far the hottest path, as every DX call will
hit this (as arm64ec functions in a vtable). L2 hits are much rarer and
L1 almost never hits since that is looked up inline in most cases.

Frontend: Force acq/rel semantics for known Unity ringbuffer offsets
...
Unity games crash with TSO disabled due to the SPSC GfxDevice
ThreadedStreamBuffer read/write pointer updates missing acq/rel
semantics. Rather than attempting to use heuristics to match cases like
this, which could be overzealous and hit more accesses than necessary, just
target the problem directly as this is consist across 32/64 bit Unity versions
for at least the past 10 years. Gate this behind the existing Unity mono
hacks to avoid false-positives in non-Unity games.

Dispatcher: Centralize SignalDelegator config creation

Since all of the information comes from the Dispatcher, we can have the dispatcher
provide that information. This way we can also eliminate a bunch of now-redundant
public interface members and simplify the config setup within InitCoreImpl().
Conveniently, this also allows making all members of the dispatcher non-public.
