Alyssa Rosenzweig eb83c9e7f2 Core: use safe CondJump for self-modifying code 
this ensures we put the StoreNZCV in the right block, which will fix validation

Billy Laws 526e3e654f LookupCache: Track ARM64EC page state in the code cache 
Rather than checking the actual EC bitmap in the dispatcher (~6 instrs), this
indirection through the code cache allows just 1 instr for the hot path
of calling repeated EC code/x64 code.

Billy Laws 243bb45a68 FEXCore: Support x64 -> arm64ec calls 
The frontend will provide the return logic via ExitFunctionEC, which
will be jumped to whenever there is an indirect branch/return to an addr
such that RtlIsEcCode(addr) returns true.

Alyssa Rosenzweig 982391ba9d IR: add ShiftFlags op 
Generates flags for a variable shift as a dedicated IR op. This lets us optimize
around it (without generating control flow, relying on deferred flag infra,
etc). And it neatly solves our RA problem for shifts.

Alyssa Rosenzweig 859df5e0b2 OpcodeDispatcher: optimize shl flag 
This is something the new shift flag code will do. Backporting the opt since
that's stalled and this reduces the diff.
