Check for incompatible pointer sign extension

gcc/

PR rtl-optimization/52876
* emit-rtl.c (set_reg_attrs_from_value): Handle arbitrary value.
Don't call mark_reg_pointer for incompatible pointer sign
extension.

* reginfo.c (reg_scan_mark_refs): Call set_reg_attrs_from_value
directly.

gcc/testsuite

PR rtl-optimization/52876
* gcc.target/i386/pr52876.c: New.
