Check if sinking I's operands to I's basic block is profitable, because the operands can be folded into a target instruction, e.g.

splats of scalars can fold into vector instructions.

bool RISCVTTIImpl::shouldConsiderAddressTypePromotion ( const Instruction & I,

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.
