v2: https://gcc.gnu.org/pipermail/gcc-patches/2021-September/579976.html Changes in v3: * Do not propagate bias along tcc_references. * Call get_rank () before checking biased_names. * Add loop-carried phis to biased_names. * Move the propagate_bias_p () call outside of the loop. * Test with -ftree-vectorize, adjust expectations.
