Parser should work with dumps from different phases

[GoogleCodeExporter]

Currently our parser works only with dumps "after CFG build".

It should be able to process dumps from any phase. If there are several
dumps of the same function, but from different phases, parser should
suggest the user to choose one from them.

Finally, parser should cope with files, that contain dumps of several
functions from different phases as well as some trash (like warning
messages from compiler).
