Ng Zhi An 6b6c1b4f11 [wasm-simd][liftoff][arm][arm64] Implement replace_lane 
All 6 replace_lane operations for ARM and ARM64.

Changes to wasm-compiler required for ARM (where register aliasing is
different - 2 fp registers map to 1 simd register). When src2_rc is
kFpReg, and src1_rc is kFpRegPair, we still need to pin src2 when
getting a register for src1, since the registers can overlap. (On other
backends, src1_rc == src2_rc == kFpReg, so the current condition is met,
and we correctly pin src2). Same for result_rc and src2_rc.
