  Log Message:
  -----------
  [msan] Add interceptors for Linux 64-bit stat variants

glibc >= 2.33 uses shared functions for stat family functions.
D111984 added support for non-64 bit variants but they
do not appear to be enough as we have been noticing msan
errors on 64-bit stat variants on Chrome OS.
