    M llvm/test/Transforms/SLPVectorizer/RISCV/strided-loads-vectorized.ll

  Log Message:
  -----------
  [SLP]Introduce transformNodes() and transform loads + reverse to strided loads.

Introduced transformNodes() function to perform transformation of the
nodes (cost-based, instruction count based, etc.).
Implemented transformation of consecutive loads + reverse order to
strided loads with stride -1, if profitable.
