re PR middle-end/35800 (Revision 133835 failed to compile binutils)
PR middle-end/35800
* expr.h (try_casesi): Adjust prototype.
* expr.c (try_casesi): Take fallback label as extra parameter.
Use that for gen_casesi if default_label is NULL.
* stmt.c (expand_case): Pass fallback label to try_casesi,
make sure to fill gaps with a fallback label if default_label
is not present.
