[truetype] Streamline backward compatibility. The 'backward_compatibility' is only set in v40: no need to check the interpreter version again and again. In addition, we now track IUP in its lower bits. After both IUPx and IUPy have been called, 'backward_compatibility' becomes equal to 0x7. * src/truetype/ttinterp.h (TT_ExecContextRec): Wrap 'iup?_called' into 'backward_compatibility'. * src/truetype/ttinterp.c (Ins_INSTCTRL): Sync 'backward_compatibility'. (Direct_Move, Direct_Move_X/Y, Move_Zp2_Point, Ins_FLIPPT,FLIPRGON,FLIPRGOFF,SHPIX,DELTAP): Updated. (TT_RunIns): Do not mess with IUP flags. * src/truetype/ttgload.c (tt_loader_init): Set 'backward_compatibility'. (TT_Hint_Glyph): Updated.
