tree-optimization/41320 - remove bogus XFAILed testcase
gcc.dg/tree-ssa/forwprop-12.c looks for reconstruction of an
ARRAY_REF from pointer arithmetic and dereference. That's not
safe because ARRAY_REFs carry special semantics we later exploit
during data dependence analysis.
The following removes the testcase, closing the bug as WONTFIX.

* gcc.dg/tree-ssa/forwprop-12.c: Remove.
