Provide debug_backtrace with proper args
Provide debug_backtrace with proper args

This would fail if we were using strict mode with php 7, because true is
only a valid argument for php < 5.3.6.
This was changed from PHP_VERSION_ID >= 50400 ?
DEBUG_BACKTRACE_IGNORE_ARGS | DEBUG_BACKTRACE_PROVIDE_OBJECT : true in
 #18272, but I do not understand why it was simplified, nor why
DEBUG_BACKTRACE_IGNORE_ARGS was there at that time.
