    ubsan: Fix ICEs with DECL_REGISTER tests [PR101624]

    The following testcase ICEs, because the base is a CONST_DECL for
    the Fortran parameter, and ubsan/sanopt uses DECL_REGISTER macro on it.
     /* In VAR_DECL and PARM_DECL nodes, nonzero means declared `register'.  */
     #define DECL_REGISTER(NODE) (DECL_WRTL_CHECK
(NODE)->decl_common.decl_flag_0)
    while CONST_DECL doesn't satisfy DECL_WRTL_CHECK.

    The following patch checks explicitly for VAR_DECL/PARM_DECL/RESULT_DECL
    only before using DECL_REGISTER, assumes other decls aren't DECL_REGISTER.
    Not really sure about RESULT_DECL but it at least satisfies
DECL_WRTL_CHECK...

    ubsan: Fix ICEs with DECL_REGISTER tests [PR101624]

    The following testcase ICEs, because the base is a CONST_DECL for
    the Fortran parameter, and ubsan/sanopt uses DECL_REGISTER macro on it.
     /* In VAR_DECL and PARM_DECL nodes, nonzero means declared `register'.  */
     #define DECL_REGISTER(NODE) (DECL_WRTL_CHECK
(NODE)->decl_common.decl_flag_0)
    while CONST_DECL doesn't satisfy DECL_WRTL_CHECK.

    The following patch checks explicitly for VAR_DECL/PARM_DECL/RESULT_DECL
    only before using DECL_REGISTER, assumes other decls aren't DECL_REGISTER.
    Not really sure about RESULT_DECL but it at least satisfies
DECL_WRTL_CHECK...
