  Log Message:
  -----------
  [hwasan] Don't check code model if there are no globals (#131152)

Currently, the code model check is always performed even if there are no
globals, because:
1) the HWASan compiler pass always leaves a note
2) the HWASan runtime always performs the check if there is a HWASan
globals note.
This unnecessarily adds a 2**32 byte size limit.

This patch elides the check if the globals note doesn't actually contain
globals, thus allowing larger libraries to be successfully instrumented
without globals.
