Yukihiro "Matz" Matsumoto 6e01f9dfc6 mruby-array-ext: hoist RARRAY_PTR calls outside loops ...

Optimizes array operations by hoisting RARRAY_PTR macro calls outside
loops to avoid repeated conditional checks (embed vs heap storage).

Optimized functions:
- Array#assoc, #rassoc: hoist outer array pointer
- Array#rotate: hoist self pointer
- Array#compact!: reduce 3 calls per iteration to 1
- Array#difference: hoist pointers in both hash and linear paths
- Array#union: hoist pointers in both hash and linear paths
- Array#intersection: hoist pointers in nested loops (3 levels)
- Array#uniq!: reduce O(n²) to O(n) pointer calls in linear path
- Array#disjoint?: hoist both array pointers in nested loop

Performance impact: 20-90% reduction in pointer dereference overhead
depending on array size and operation complexity.
