gimplify_modify_expr: avoid DECL_DEBUG_EXPR links across functions

An upcoming patch exposes a bug in gimplify_modify_expr.  There, we try
not to create DECL_DEBUG_EXPR links across functions, however we don't
check that *FROM_P actually belongs to the current function before
modifying it.  This patch fixes this oversight.

gcc/

* gimplify.c (gimplify_modify_expr): Don't create a
DECL_DEBUG_EXPR link if *FROM_P does not belong to the current
function.
