Aaron Klotz e311b07d92 Bug 1532470: Part 4 - Add 4-byte patching to ARM64 interceptor; r=handyman 
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).
