PATCH 1: Add WHILE_LEN pattern in Loop Vectorizer to support decrement IV for RVV.
PATCH 2: Enable basic auto-vectorization for RVV in RISC-V port.
PATCH 3: Add testcases for basic RVV auto-vectorization of WHILE_LEN pattern 
         includeing single rgroup test and multiple rgroup test of SLP.

*** BLURB HERE ***

Juzhe-Zhong (3):
  VECT: Add WHILE_LEN pattern to support decrement IV manipulation for
    loop vectorizer.
  RISC-V: Enable basic RVV auto-vectorization and support
    WHILE_LEN/LEN_LOAD/LEN_STORE pattern
  RISC-V: Add testcase for basic RVV auto-vectorization
