a gcc plugin to show cfg graphically when debug gcc

[Eric Fisher]

Hi,

I just wrote a little gcc plugin, which can be used to show GIMPLE cfg
graphically when debug gcc. Currently, it's still a very initial
version. It,
  * transfers tree dump into vcg file,
  * then invokes vcgview (or aisee etc.) to show the graph.

I would like to improve it to support both tree level and rtl level
vcg visualization later.

Any suggestions would be appreciated.
