Store the bytecode offset in thread_statefeature/zach-soc-bytecode-in-traceback
* src/lisp.h: * src/eval.c (backtrace_byte_offset): Remove global variable, and put it... * src/thread.h (thread_state): ...in here as m_backtrace_byte_offset, and define backtrace_byte_offset as a macro that points to it. * src/bytecode.c (UPDATE_OFFSET): Move out of #ifdef BYTE_CODE_THREADED.
