elliottt opened PR #5366 from trevor/ssa-aarch64-load-constant to main:

As loading constants on aarch64 can take up to 4 instructions, we need to plumb through some additional registers. Rather than pass a fixed list of registers in, pass an allocation function.

This forced a change to ABIMachineSpec::gen_memcpy, as it now needed to take an allocator to pass to uses of gen_constant. As a result, I removed the fixed temporary arguments and passed an allocator instead.

The two consecutive calls to load_constant are what's forcing the alloc_tmp argument to load_constant to be a mutable reference.
