This patch modifies arm64 so that detours are peformed via two passes: 1. The first pass uses a null trampoline to count how many bytes are available for patching the original function. 2. If we have >= 16 bytes to patch, we reuse existing trampoline space. If we have less than 16 bytes to patch, we reserve trampoline space within 128MB of the function, allowing for a 4 byte patch. 3. Then we recurse, this time using a real trampoline. Note that we still do a single-pass on x86(-64).
