We weren't setting its size, which caused problems when `__llvm_addrsig`
wasn't the last section. In particular, `__debug_line` (if created) is
generated and placed after `__llvm_addrsig`, and would result in an
invalid object file w/ overlapping sections being emitted.

Unfortunately, we have to iterate over all the addrsig symbols to
calculate the section size, but I'm not sure there's a better way to do
this.
