  Log Message:
  -----------
  [SelectionDAGBuilder][RISCV] Fix crash when using a memory constraint with scalable vector type. (#99821)

We need to use the minimum size of the scalable type and the correct
stack ID.

The code in the PR is still invalid because the instruction used doesn't
have a pointer operand. This is diagnosed later when the assembler
parses it.

Fixes #99782
