Add debugger functionality to pause the VM whenever a TypeError
or AssertionError exception happens.
This is a first step towards breaking on handled and unhanded
exceptions in general. We first need to generate more debug info
for catch handlers so we can determine whether an exception will
be handled or not before we unwind the stack to run the catch
clauses.

- Single step now steps to a safe point on the next line.
- Step into no longer steps into library code.
- Each library has a flag that specifies whether one
can step into its code.
Later I will add an API to set the per-library flag. Currently
it's set to true for the top-level library and to false for
all other libraries.

- Adding commands to set breakpoints and showing current stack trace.
- Adding a callback hook to signal when a breakpoint gets resolved to
and actual line number.
- Adding ids for breakpoints and new breakpoint API functions, deprecating
the existing ones.
- Adding one helper function to the JSON class
Anton may want to take a look at the JSON addition.

Local functions and function literals are unknown to the VM
until the enclosing function is compiled. This change introduces
a list of known closures per class, and a function to look up
the innermost closure at a given token index.
The debugger now checks whether there are newly discovered
closures when a function containing a pending breakpoint is
compiled. If necessary, the breakpoint is set to the inner
function.

Splitting breakpoints into SourceBreakpoint that represent
a user-defined source location of a breakpoint, and
CodeBreakpoint, which represents a code location. There can
be more than one CodeBreakpoint per SourceBreakpoint, e.g.
for functions that are also called as closures (and are thus
compiled twice.)
Functions are no longer compiled as a side effect of setting
a breakpoint. When they eventually get compiled, the previously
recorded SourceBreakpoint is found and a CodeBreakpoint is set.

This function can be used in native functions to properly pass all
errors up the stack.
Set the long jump base in the Compiler instead of outside of the
compiler. A bunch of errors that used to be propagated through the
sticky_error are now propagated through return values. This includes
all of the DartEntry and DartLibraryCall functions.
In particular, we no longer use the long jump to cross dart frames.
Instead errors are propagated across dart frames using the same
mechanism that we use for unhandled exceptions. I've added assertions
to make sure that we only use the long jump when it is "safe".

This change introduces variable descriptors that describe the name, stack slot index, and source code stretch in which a variable is valid.
Activation frames in the stack trace now can enumerate the variables that are active in that frame.
Next step: fetch the value of variables from the stack.
