[ELF] Fix IRELATIVE addend if the resolver address is updated by linker relaxation (#179063)
For a non-preemptible ifunc, `handleNonPreemptibleIfunc` creates a
cloned
symbol (`directSym`) to compute the addend of the IRELATIVE dynamic
relocation.
This cloned symbol wasn't tracked by `initSymbolAnchors`, so its value
wasn't adjusted during RISC-V/LoongArch linker relaxation.
This caused IRELATIVE addends to point to pre-relaxation addresses.

Fix this by:

- Tracking cloned IRELATIVE symbols in `ctx.irelativeSyms`
- Adding these symbols to `relaxAux->anchors` in `initSymbolAnchors`
