As the extern_weak target might be missing, resolving to the absolute
address zero, we can't use the normal direct PC-relative branch
instructions (as that would result in relocations out of range).
Instead check the shouldAssumeDSOLocal method and load the address
from a COFF stub.
This matches what was done for X86 in 6bf108d77a.
