    AArch64: Use SVE unpredicated LOGICAL expressions when Advanced SIMD
inefficient [PR109154]

    SVE has much bigger immediate encoding range for bitmasks than Advanced
SIMD has
    and so on a system that is SVE capable if we need an Advanced SIMD
Inclusive-OR
    by immediate and would require a reload then use an unpredicated SVE ORR
instead.

    This has both speed and size improvements.
