  Log Message:
  -----------
  [RISCV] Don't merge pseudo selects with stack adjustment instrs in between (#160105)

When we have sequence of select pseudo instructions with stack adjustment
instructions in between, we shouldn't apply the optimization, proposed by link 
https://reviews.llvm.org/D59355. If optimization is applied, 
function won't be marked `adjustsStack` during Finalize ISel pass.
