  Log Message:
  -----------
  Revert "[BasicAA] Use known lower bounds for index values for size based check."

This potentially related to https://bugs.llvm.org/show_bug.cgi?id=46335
and causes a slight compile-time regression. Revert while investigating.

This reverts commit d99a1848c4f8ca164c0c0768e10eafc850b2a68a.
