  [lldb] Make `print` delegate to synthetic frames.

This patch is more of a proposal in that it's a pretty dramatic change to the way that `print` works. It completely delegates getting values to the frame if the frame is synthetic, and does not redirect at all if the frame fails.

For this patch, the main goal was to allow the synthetic frame to bubble up its own errors in expression evaluation, rather than having errors come back with an extra "could not find identifier <blah>" or worse, simply get swallowed. If there's a better way to handle this, I'm more than happy to change this as long as the core goals of 'delegate variable/value extraction to the synthetic frame', and 'allow the synthetic frame to give back errors that are displayed to the user' can be met.
