Various AArch64 optimizations (https://github.com/Shopify/ruby/pull/433)
* When we're storing an immediate 0 value at a memory address, we
can use STUR XZR, Xd instead of loading 0 into a register and
then storing that register.
* When we're moving 0 into an argument register, we can use
MOV Xd, XZR instead of loading the value into a register first.
* In the newarray instruction, we can skip looking at the stack at
all if the number of values we're using is 0.
