LoongArch: Fix R_LARCH_IRELATIVE insertion after elf_link_sort_relocs
loongarch_elf_finish_dynamic_symbol is called after elf_link_sort_relocs
if -z combreloc. elf_link_sort_relocs redistributes the contents of
.rela.* sections those would be merged into .rela.dyn, so the slot for
R_LARCH_IRELATIVE may be out of relplt->contents now.
To make things worse, the boundary check
dyn < dyn + relplt->size / sizeof (*dyn)
is obviously wrong ("x + 10 < x"? :), causing the issue undetected
during the linking process and the resulted executable suddenly crashes
at runtime.
The issue was found during an attempt to add static-pie support to the
toolchain.
Fix it by iterating through the inputs of .rela.dyn to find the slot.
