LoongArch: ld: Fix other pop relocs overflow check and add tests

Add reloc_unsign_bits() to fix others sop_pop relocs overflow check.
Then add over/underflow tests for relocs B*, SOP_POP* and PCREL20_S2.

bfd/ChangeLog:

	* bfd/elfxx-loongarch.c: Add reloc_unsign_bits().

ld/ChangeLog:

	* ld/testsuite/ld-loongarch-elf/ld-loongarch-elf.exp: Add tests.
