cfgcleanup.c (outgoing_edges_match, [...]): Remove CASE_DROPS_THROUGH checks, it is never defined.
* cfgcleanup.c (outgoing_edges_match, try_crossjump_to_edge):
Remove CASE_DROPS_THROUGH checks, it is never defined.
* cfglyout.c (fixup_reorder_chain): Likewise.
* cfgrtl.c (rtl_verify_flow_info): Likewise.
* stmt.c (expand_case): Likewise.
* cfgbuild.c (make_edges): Likewise. Also remove force_fallthru,
it is now always 0.
* system.h (CASE_DROPS_THROUGH): Poison.
* doc/md.texi (casesi): Remove documentation of CASE_DROPS_THROUGH.
* doc/tm.texi (casesi): Remove documentation of CASE_DROPS_THROUGH.
* config/v850/v850.h: Remove commented out CASE_DROPS_THROUGH.
