  [truetype] Reset IUP flags in `TT_RunIns`.
  
  Fixes #1148 by moving the flag initialization back, partly reverting
  7809007a and fd03dcc1.  Initializing these flags elsewhere skips 'cvt'.
  
  * src/truetype/ttinterp.c (TT_RunIns): Initialize the IUP flag here...
  (TT_Run_Context): ... instead of here.
