[Mono-devel-list] optimizing foreach on strings

[Varga Zoltan]

                                           Hi,

  The attached patch adds an optimization to mcs so it
generates more
efficient code for
    foreach (char c in <STRING>)
The optimized code avoids the try-finally block and the
boxing. The same
optimization is done by the MS compiler.

I ran a full bootstrap and the regression test with it and
it seems ok.
Could somebody review the patch?

              thanks

                      Zoltan
