The new PTA code also uncovered a "bug" in gimple-fold which I opened
PR 123160 for.
Until that is fixed, the new PTA code triggers a testcase failure in
gcc.dg/builtin-object-size-4.c
I plan to check in the following patch which can then be reverted or
adjusted when that PR is fixed.
IF anyone has an alternate suggestion, please let me know.
