It originates from the era where we used to run a separate preparse step
before parsing and store the function data. Now the usage of preparser
is something completely different, so this flag doesn't make sense any
more.
In addition, this way we get more test coverage for preparser (for small
scripts).

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()

Lexically declared "arguments" in sloppy mode will throw redeclaration error
currently, this patch fixes it by delaying the declaration of arguments until we
fully parse parameter list and function body.

Added a new %HasComplexElements runtime function (meaning elements that are
non-writable, non-configurable, or have getters and setters) and use it
in UseSparseVariant to filter out cases where the sparse optimizations
can cause V8 to fall out of spec compliance.
Renamed SmartMove/SmartSlice to SparseMove/SparseSlice and guarded them
with the new and improved UseSparseVariant.
These two changes combine let us pass nearly every test in bug-2615.js,
as well as fixing reverse and join on sparse arrays.
Note that there are various test changes in this patch that correct existing
tests to match the correct-by-spec behavior.
This patch depends on https://codereview.chromium.org/666883009, which
better-aligns the behavior of SmartMove with SimpleMove.

When a function is called with a value type as the receiver this is now boxed as an object.
This is a low-impact solution where the receiver is only boxed when required. For IC calls to the V8 builtins values are not boxed and as most of the functions on String.prototype, Number.prototype and Boolean.prototype are sitting there most IC calls on values will not need any boxing of the receiver.
For calls which are not IC calls but calls through the CallFunctionStub a flag is used to determine whether the receiver might be a value and only when that is the case will the receiver be boxed.
No changtes to Function.call and Function.apply - they already boxed values. According to the ES5 spec the receiver should not be boxed for these functions, but current browsers have not adopted that change yet.
