◆ shouldConsiderAddressTypePromotion()

bool AArch64TTIImpl::shouldConsiderAddressTypePromotion	(	const Instruction &	I,
		bool &	AllowPromotionWithoutCommonHeader
	)

See if I should be considered for address type promotion.

We check if I is a sext with right type and used in memory accesses. If it used in a "complex" getelementptr, we allow it to be promoted without finding other sext instructions that sign extended the same initial value. A getelementptr is considered as "complex" if it has more than 2 operands.
