Alyssa Rosenzweig 77415538f7 OpcodeDispatcher: use 64-bit XOR for AF calc 
we don't need masking and the masking gets in the way of constprop.

Billy Laws 981c3009ee FEXCore: Emulate EFLAGS.TF 
When set - either via POPF or a thread context operation - the trap flag
raises a single step exception after the execution of each instruction.
As e.g. a JUMP instruction with TF set will raise an exception at the
jump target. Handle this on the FEX side by storing both the flag itself
(in bit 0) and a 'block exceptions' flag (in bit 1, inverted). Each
generated block when TF is set is then forced to a single instruction
with logic to raise the exception at the start. Initially after setting
TF exceptions are blocked, then at the start of the block they are
unblocked so that after the instruction executes an exception is raised
at the start of the next block.

Ryan Houdek 0123946ed1 FEXCore: Removes GetGPRSize and convert all uses to GetGPROpSize 
Only a few remaining uses left, easy enough to convert. This finally
switches the final few uses over.

Alyssa Rosenzweig aeb2c98cbf OpcodeDispatcher: drop PossiblySetNZCV 
this is a pain to track and, it turns out, buys us virtually nothing on flagm
systems. rip it out.

this fixes a bug with failing to set in all the right places.

on non-flagm systems there's a slight instcountci impact, but that is mostly
mitigated by the earlier patches in the series. so overall a wash there but
worth it for making the codebase easier
to reason about.

Ryan Houdek 1465df874b OpcodeDispatcher: Fixes 80-bit loads 
Ensures reads don't go past the end of the page boundary.
SVE masked loads can make this more effective but `VLoadVectorMasked`
isn't setup to be efficient for this case yet.

Ryan Houdek 9b6cc8f7e0 IR: Convert OpSize over to enum class 
NFC

Do the final mopping up to convert the OpSize enum to an enum class!

Ryan Houdek 82f936cb6d IR: Converts base IR operations to store OpSize sizes 
NFC

Finally converts the IR operations themselves to store the OpSize for
the IR operation size and element sizes.

This also finally, FINALLY, converts that remaining `_Constant` helper
to stop using a size field that is specified in bits rather than bytes
like all the other IR op handlers. That thing was so confusing and now
it's gone.

Plus the tertiary bits that require changing to support it.
