position collection lazier\n\nPreviously when lazy source positions were enabled, source positions\nwere immediately collected whenever an exception was thrown for every\nframe in the stack trace.\n\nThis change makes source position collection trigger only when the\nsource positions of a stack frame are actually accessed with the\nexception of the top frame which is still eagerly collected for now.\n\nAdditionally when stack overflows occur during source position\ncollection, the bytecode is marked with exception in the\nsource_position_table field so it can be distinguished from the case\nwhere source position collection has never been attempted (undefined)\nor is not desired because the bytecode is for natives\n(empty_byte_array).\n\nBug: v8:8510\nChange-Id:
