          Issue Type: Improvement
          Components: DRLVM
            Reporter: Mikhail Fursov
            Assignee: Mikhail Fursov

This patch contains a set of independent improvements done by me while preparing bc-level
edge profile and lazy resolution mode enabling in Jitrino.OPT
The list of improvements:

1) Improved bcmapping checking -> developer now gets error about illegal bcmapping in IR
earlier
2) Some compile time warnings fixed
3) Loop normalization algorithm now produce nodes with bc-mapping
4) Unresolved method type now have param/return types information
5) Nodes created by devirtualizer now have valid bcmapping
6) IR/DOT dumps  now work for inlined methods too
7) All nodes in IR now can be asked about start/end bc-map location (this info derived from
insts in the node)
8) Translator now dumps bytecode into log. It simplifies reading translator's logs.
