AArch64: improve 64-bit immediates loads. Improve the quick backend to load immediates by choosing the best of the following strategies: - use wzr, xzr to load 0 (via mov) or -1 (via mvn), - use logical immediates (orr), - use one movz/movn optionally followed by one or more movk, - use the literal pool.
