    middle-end/94479 - fix gimplification of address

    When gimplifying an address operand we may expose an indirect
    ref via DECL_VALUE_EXPR for example.  This is dealt with in the
    code already but it fails to consider that INDIRECT_REFs get
    gimplified to MEM_REFs.

    Fixed which makes the ICE observed on x86_64-netbsd go away.

            * gimplify.c (gimplify_addr_expr): Also consider generated
            MEM_REFs.

            * gcc.dg/torture/pr94479.c: New testcase.

Fixes -fstack-check ICE when building devel/git-base.
