Here we have the patch for gold aarch64 backend to support relaxation.
In short relaxation is the linker's generation of stubs that fixes the
out-of-range jumps/branches in the original object file.
With this implementation, we are able to link a 456MB aarch64 application.
Tested:
1) Build natively on x86_64 and aarch64 machines.
2) Pass unit tests regarding relaxation.
