tree-optimization/106866 - avoid dead abnormal edges from DCE
When DCE clears cfun->calls_setjmp then suddenly we don't need
any abnormal call edges anymore. The following makes sure to
prune them which otherwise can confuse other passes.
PR tree-optimization/106866
* tree-ssa-dce.cc (eliminate_unnecessary_stmts): When
we changed cfun->calls_setjmp make sure to purge all
abnormal call edges.
* gcc.dg/uninit-pr106866.c: New testcase.
