Hi Alexey, After your patch Clang crashes while building 453.povray for aarch64-linux-gnu. Apparently, this happens only with LTO enabled at -O2 and -O3.

If the extractelement instruction is used multiple times in the different tree entries (either vectorized, or gathered), need to compensate the scalar cost of such instructions. They are completely removed if all users are part of the tree but we need to compensate the cost only once for each instruction.
