Improve performance for stepping

We need to cache more data from the debugged JVM:

  • loaded classes
  • anonymous functions/line numbers
  • (maybe) constant pool data when skipping Forwarders

(original ticket follows):

The scene is configured in the same way as here: http://www.assembla.com/spaces/scala-ide/support/tickets/1001000-scala-debugger-is-confused-when-stepping-into.

Go to Macros.scala, and navigate to "def macroExpand(". Put the breakpoint on the first breakpointable line of the method and try to debug any macro expansion (e.g. open test/files/run/macro-basic-ma-mdmi, pre-compile Impls_Macros_1.scala and debug scalac -language:experimental.macros Test_2.scala). Try to make a few Step Overs. Now switch to the vanilla debugger and repeat. Will me much faster.

We decided to postpone this to the next sprint, as it will require considerable work.

(In scala-ide:f6b586a8e05bdea4c61b98a28dcdb392f8b4981e) Integrated the debug cache to the debugger

It is used in for breakpoints and step-over.
Fixes the first part of the ticket: nested classes.
