in fold_builtin_[123], replace `TREE_CODE (*) == ERROR_MARK` with
`error_operand_p (*)` will fix this.

The trunk branch has been updated by Andrew Pinski <pinskia@gcc.gnu.org>:
https://gcc.gnu.org/g:dbe9062ce070c861cd3fa6435187618413b1b3d1
commit r14-9613-gdbe9062ce070c861cd3fa6435187618413b1b3d1
Author: Andrew Pinski <quic_apinski@quicinc.com>
Date: Thu Mar 21 16:29:20 2024 -0700
Another ICE after conflicting types of redeclaration [PR109619]
This another one of these ICE after error issues with the
gimplifier and a fallout from r12-3278-g823685221de986af.
This case happens when we are trying to fold memcpy/memmove.
There is already code to try to catch ERROR_MARKs as arguments
to the builtins so just need to change them to use error_operand_p
which checks the type of the expression to see if it was an error mark
also.
Bootstrapped and tested on x86_64-linux-gnu with no regressions.
gcc/ChangeLog:
PR c/109619
* builtins.cc (fold_builtin_1): Use error_operand_p
instead of checking against ERROR_MARK.
(fold_builtin_2): Likewise.
(fold_builtin_3): Likewise.
gcc/testsuite/ChangeLog:
PR c/109619
* gcc.dg/redecl-26.c: New test.
