…ions Now we recognize the full set of hardware supported immediate operands. `is_logical_immediate` was moved from Selection to Arch and made to work on nativeints. This is in preparation for future use in Emit.
Add a special case for immediates that can be loaded in one "or" instruction. Refactor the code that produces sequences of movz/movn/movk to be less redundant and to choose the shortest sequence between the "movz" sequence and the "movn" sequence.

* ARM64: improve recognition of immediate operands for logical instructions Now we recognize the full set of hardware supported immediate operands. `is_logical_immediate` was moved from Selection to Arch and made to work on nativeints. This is in preparation for future use in Emit. * ARM64: Improve code generation for load integer immediate Add a special case for immediates that can be loaded in one "or" instruction. Refactor the code that produces sequences of movz/movn/movk to be less redundant and to choose the shortest sequence between the "movz" sequence and the "movn" sequence. * ARM64: add and recognize specific operation for sign extension * Fix compilation Co-authored-by: Xavier Leroy <xavier.leroy@college-de-france.fr>
