LoongArch: Fix bad reloc with mixed visibility ifunc symbols in shared libraries
With a simple test case:
.globl ifunc
.globl ifunc_hidden
.hidden ifunc_hidden
.type ifunc, %gnu_indirect_function
.type ifunc_hidden, %gnu_indirect_function
.text
.align 2
ifunc: ret
ifunc_hidden: ret
test:
bl ifunc
bl ifunc_hidden
"ld -shared" produces a shared object with one R_LARCH_NONE (instead of
R_LARCH_JUMP_SLOT as we expect) to relocate the GOT entry of "ifunc".
It's because the indices in .plt and .rela.plt mismatches for
STV_DEFAULT STT_IFUNC symbols when another PLT entry exists for a
STV_HIDDEN STT_IFUNC symbol, and such a mismatch breaks the logic of
loongarch_elf_finish_dynamic_symbol. Fix the issue by reordering .plt
so the indices no longer mismatch.
