[lld][ELF][test] Expand testing of symbols in mergeable sections Whilst reviewing some internal testing, I noticed a couple of holes in coverage of mergeable sections containing symbols. This patch addresses these holes: 1) Show that mid-piece symbols have their values updated properly when pieces are merged. 2) Show the behaviour of symbols in mergeable pieces when --gc-sections is enabled.
