  [LoongArch][MC] Refine MCInstrAnalysis based on registers used (#71276)

MCInstrAnalysis can return properties of instructions (e.g., isCall(),
isBranch(),...) based on the informations that MCInstrDesc can get from
*InstrInfo*.td files. These infos are based on opcodes only, but JIRL
can have different properties based on different registers used.

So this patch refines several MCInstrAnalysis methods: isTerminator,
isCall,isReturn,isBranch,isUnconditionalBranch and isIndirectBranch.

This patch also allows BOLT which will be supported on LoongArch later
to get right instruction infos.
