Jean-Didier PAILLEUX d6c6bde9db [flang] Implement !DIR$ UNROLL_AND_JAM [N] (#125046) ...

This patch implements support for the UNROLL_AND_JAM directive to enable
or disable unrolling and jamming on a `DO LOOP`.
It must be placed immediately before a `DO LOOP` and applies only to the
loop that follows. N is an integer that specifying the unrolling factor.
This is done by adding an attribute to the branch into the loop in LLVM
to indicate that the loop should unrolled and jammed.
