RISCV,LoongArch: Encode RELAX relocation implicitly
When linker relaxation is enabled, relaxable relocations are followed by
a R_RISCV_RELAX/R_LARCH_RELAX relocation. They are encoded as two fixups by
CodeEmitter and expected to have the same `IsResolved` value within
MCAssembler::evaluateFixup (they must lead to either 0 or 2
relocations). This scheme wasite space and requires RISCVAsmBackend::shouldForceRelocation
to be conservative.
This patch introduces MCFixup::NeedsRelax to encode the RELAX relocation implicitly.
The fixup will lead to either 0 or 2 relocations.
