A complete implementation of `applyFixup` for D132323 <https://reviews.llvm.org/D132323>.

Makes `LoongArchAsmBackend::shouldForceRelocation` to determine
if the relocation types must be forced.

This patch also adds range and alignment checks for `b*` instructions'
operands, at which point the offset to a label is known.

Depends on D132633 <https://reviews.llvm.org/D132633>
