Do not use DW_OP_not for TRUTH_NOT_EXPR in conditional expressions

DW_OP_not is a bitwise, not a logical NOT, so it computes the wrong result
in a DWARF conditional expression.

gcc/
* dwarf2out.cc (loc_list_from_tree_1) <TRUTH_NOT_EXPR>: Do a logical
instead of a bitwise negation.
<COND_EXPR>: Swap the operands if the condition is TRUTH_NOT_EXPR.
