  ELF: -r: Call assignAddresses only once

The fixed-point layout algorithm handles linker scripts, thunks, and
relaxOnce (to suppress out-of-range GOT-indirect-to-PC-relative
optimization). These passes are not needed for relocatable links because
they require address information that is not yet available.

Since we don't scan relocations for relocatable links, the
`createThunks` and `relaxOnce` functions are no-ops anyway, making these
passes redundant.

To prevent cluttering the line history, I place the `if (...) break;`
inside the for loop.
