This CL further extends the debug wrapper, migrates around 60 tests, and
removes a few tests that use functionality we will not support anymore.
In more detail:
* Removed tests that use:
* enable/disable individual breakpoints
* invocationText()
* the ScriptCollected event
* showBreakPoints
* evalFromScript (and similar)
* mirror.constructedBy and mirror.referencedBy
* event_data.promise()
* Some frame.evaluate uses were adapted since due to differences between
remote objects (inspector) and mirrors. For instance, exceptions are
currently not recreated exactly, since the inspector protocol does not
give us the stack and message separately. Other objects (such as
'this' in debug-evaluate-receiver-before-super) need to be explicitly
converted to a string before the test works correctly.
* Ensure that inspector stores the script before sending ScriptParsed and
ScriptFailedToParse events in order to be able to use the script from
within those events.
* Better remote object reconstruction (e.g. for undefined and arrays).
* New functionality in wrapper:
* debuggerFlags().breakPointsActive.setValue()
* scripts()
* execState.setVariableValue()
* execState.scopeObject().value()
* execState.scopeObject().property()
* execState.frame().allScopes()
* eventData.exception()
* eventData.script()
* setBreakPointsActive()

This CL adds support for:
* conditional breaks in setBreakpoint,
* locals in frame.local{Count,Name,Value},
* evaluation on a frame in frame.evaluate,
* and more detailed scope information in scopeObject.
Uses of several functions that are not covered by the
inspector protocol and are only used in tests have been removed.
Local handling has been modified to also include arguments as locals.
Inspector differs in this regard from our FrameDetails in that
arguments are always shown as locals. Argument-related functions
were removed.

This adds clearStepping plus the family of
{set,clear}BreakOn{,Uncaught}Exception functions.

This CL adds further support to the test wrapper. We are now able to
run almost all mjsunit/debug-step-* tests using the inspector backend.
debug-stepframe-* tests are not yet supported since inspector does not
know a 'frame' step type.
The interface has also been improved to be able to move these tests to
inspector mostly without modification.

This CL adds simple implementation of break and stepping-related functionality
as required by the debug-step.js test. This includes
* stepOver, stepInto, stepOut
* setBreakPoint
* clearBreakPoint
* evaluate
Some of these, e.g. setBreakPoint are not fully implemented for all cases but
only for the ones we need right now.
One interesting result of this is that using the inspector protocol is roughly
14x slower for debug-step.js (14s instead of 0.5s). One cause of this seems to
be iteration over all object properties in toProtocolValue, which is used to
serialize JS objects before being sent over the wire (e.g. FrameMirrors). This
is something that should be fixed at some point. In the meantime, the test now
runs 100 instead of 1000 iterations.

This adds a wrapper class around the inspector protocol for use in
debugger tests. The interface is intended to stay similar to the
currently exposed DebuggerContext.
Right now, we support adding a listener, (partial) handling of the
AfterCompile event, and enabling/disabling the debugger.
