[RISCV] Add the DebugLoc parameter to getVLENFactoredAmount().
The MachineBasicBlock::iterator is continuously changing during
generating the frame handling instructions. We should use the DebugLoc
from the caller, instead of getting it from the changing iterator.
If the prologue instructions located in a basic block without any other
instructions after these prologue instructions, the iterator will be
updated to the boundary of the basic block and it is invalid to use the
iterator to access DebugLoc. This patch also fixes the crash when
accessing DebugLoc using the iterator.
