/* The C4x looping instruction needs to be emitted at the top of the
loop. Emitting the true RTL for a looping instruction at the top of
the loop can cause problems with flow analysis. So instead, a dummy
doloop insn is emitted at the end of the loop. This routine checks
for the presence of this doloop insn and then searches back to the
top of the loop, where it inserts the true looping insn (provided
there are no instructions in the loop which would cause problems).
Any additional labels can be emitted at this point. In addition, if
the desired loop count register was not allocated, this routine does
nothing. */
