PR c++/86678 - constexpr function with non-constant after return.
In this testcase, the call to f() can never be a constant
expression, but that's not a problem because it isn't always
reached by calls to g. We were wrongly rejecting this because
potential_constant_expression_1 lacked the jump tracking that
cxx_eval_constant_expression has. So this patch adds a simpler
version of that tracking.
* constexpr.c (potential_constant_expression_1): Add jump_target.
(breaks): Check for BREAK_STMT.
(continues): Check for CONTINUE_STMT.
