Do not erase warning data in gimple_set_location
gimple_set_location is mostly invoked on newly built GIMPLE statements, so
their location is UNKNOWN_LOCATION and setting it will clobber the warning
data of the passed location, if any.
gcc/
* dwarf2out.cc (output_one_line_info_table): Initialize prev_addr.
* gimple.h (gimple_set_location): Do not copy warning data from
the previous location when it is UNKNOWN_LOCATION.
* optabs.cc (expand_widen_pattern_expr): Always set oprnd{1,2}.
gcc/testsuite/
* c-c++-common/nonnull-1.c: Remove XFAIL for C++.
