Ryan Houdek d7afcee622 AVX128: Fixes asome AVX bugs 
vblendvps, vblendvpd, vpblendvb all broke because of failing to zext the
128-bit register correctly.

vinsertps broke because it was accidentally using the wrong
implementation.

Extends each of their unittests to handle these cases.

Paulo Matos 10ec6b63b6 Fix FXTRACT for 0.0 and -0.0 
Fixes fxtract by returning the correct values for 0.0 and -0.0. We moved the split of fxtract into _sig and _exp, to the opcode dispatcher, to ease some comparisons.

Also removed the IR node F80XTRACTStack which is not needed anymore.

Ryan Houdek e53f3969e9 FEXCore: Change yield implementation to use wfe 
According to
https://github.com/rust-lang/rust/commit/c064b6560b7ce0adeb9bbf5d7dcf12b1acb0c807
turns out that the arm yield instruction is effectively a nop on all
reasonably new CPUs.
Instead switch over to wfe because it matches x86 `PAUSE` semantics more
closely.

Ryan Houdek c740801ea5 VDSOEmulation: Support loading VDSO thunk as shared 
Just requires a thread pointer check to be fixed in FEXCore.
This doesn't need unique pages to exist for the file mapping and can be
shared since it's readonly mapped.

Ryan Houdek 7dda75646d OpcodeDispatcher: Fixes segment prefixing on vector element loadstores 
These had completely forgotten to load segment prefixes on the element
loadstore operations. This had caused a crash on the Linux version of
"Halls of Tormet" (steamid 2218750).

This game has TLS vector data which it was loading with a movhps and hit
this path.

Ryan Houdek 58bcf691d6 Linux: Optimize CreateNewThread stack usage 
We were creating a copy of the FEXCore::Core::CPUState object when we
didn't need to. We can pass the host thread's CPUState frame through to
the creation handlers since it's read-only (so modify it to be const).

We then just move the RAX and RSP setting to /after/ the CreateThread
handling instead of before.
This reduces stack usage from ~1392 bytes to ~80 bytes.

Ryan Houdek e7605c94dd SignalDelegator: Let the frontend inform AVX support 
Since the frontend has changed to informing the backend if AVX is
supported, there is no reason to feed that configuration back in to
SignalDelegator from the backend.

Instead inform the SignalDelegator directly in the frontend instead of
this now weird round-about path.

Ryan Houdek ab5a10374b FEXCore: Remove BlockSamplingData 
This was a legacy interface that has long lost its implementation and
has long lost its use. This interface was similar to an older
Dolphin-Emu interface that was useful in that project, but isn't really
useful in a world with hundreds of threads and processes running at the
same time.
