* c-semantics.c (find_reachable_label): New function to find a
potentially reachable label in an expression.
(expand_unreachable_if_stmt): Similar to expand_if_stmt but
assumes the start of the IF_STMT is unreachable (dead) code.
(expand_unreachable_stmt): Similar to expand_stmt but assumes
the start of the statement list is unreachable (dead) code.
(genrtl_if_stmt): If the controlling expression of the IF
is constant, use expand_unreachable_stmt for the THEN or ELSE
clause as appropriate.
(genrtl_switch_stmt): Use expand_unreachable_stmt to expand
the body of a SWITCH statement.
(expand_stmt): The code immediately following a "return",
"break", "continue" or "goto" is unreachable.
* Makefile.in (c-semantics.o): Depend upon tree-inline.h.
* gcc.dg/Wunreachable-5.c: New test case for PR c/10175.
* gcc.c-torture/execute/medce-1.c: New test case.
