Tony noticed this last week. I encountered it this week.
Add support for spilling and filling GPR pairs.

Alyssa Rosenzweig 7b3e031678 ValueDominanceValidation: forbid crossblock liveness 
Now that we have successfully eliminated crossblock liveness from the IR we
generate, validate as much to ensure it doesn't come back. We will take
advantage of this new invariant in RA in the future.

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.

Ryan Houdek 904646e93b FEXCore: Fixes priority of FEX_APP_CONFIG 
This environment variable had an incorrect priority on the configuration
system. The expectation was higher priority than most other layers.

Now the only layer that has higher priority is the environment
variables.
