  -----------
  [CodeGen] Merge lowerConstantIntrinsics into pre-isel lowering (#97727)

Currently, the LowerConstantIntrinsics pass does an RPO traversal of
every function... only to find that many functions don't have constant
intrinsics (is.constant, objectsize). In the CodeGen pipeline, there is
already a pre-isel intrinsic lowering pass, which iterates over
intrinsic declarations and lowers all users. Call
lowerConstantIntrinsics from this pass to avoid the extra iteration over
the entire IR and the RPO traversal.
