This mostly removes dead code and obsolete special cases from the
RawMachineAssembler::MakeNode helper, that shouldn't be necessary
anymore.

According to the ECMA spec, a 24th hour is allowed if the minutes, seconds, and milliseconds are all zero (i.e. it's midnight). Previously, we parsed the date correctly, however, we failed to account in all checks for the possibility of a 24th hour. This CL changes the check to allow a 24th hour if it's exactly midnight.

Adds basic support for generation of interpreter bytecode handler code
snippets. The InterpreterAssembler class exposes a set of low level,
interpreter specific operations which can be used to build a Turbofan
graph. The Interpreter class generates a bytecode handler snippet for
each bytecode by assembling operations using an InterpreterAssembler.
Currently only two simple bytecodes are supported: LoadLiteral0 and Return.

All of this is controlled by the CallDescriptor. It's simply the case
that if you specify less registers than the function arity calls for,
the rest are assumed to be on the stack.
Bailout handlers accept these constant stack arguments too.

Previous to this CL, ICs used a slightly different code idiom
to get to C++ code from generated code than runtime intrinsics,
using an IC_Utility class that in essence provided exactly
the same functionality as Runtime::FunctionForId, but in its
own quirky way.
This CL unifies the two mechanisms, folding IC_Utility
away by making all IC entry points in C++ code, e.g. IC
miss handlers, full-fledged runtime intrinsics. This makes
it possible to eliminate a bunch of ad-hoc declarations and
adapters that the IC system had to needlessly re-invent.
As a bonus and the original reason for this yak-shave:
IC-related C++ runtime functions are now callable from
TurboFan.

Using the GraphBuilder base class forces each node creation to go
through a virtual function dispatch just for the sake of saving the
duplication of the NewNode helper methods. In total that added up to
saving minus (sic!) six lines of code.

There is already non-throwing version FrameMirror.restart and RestartFrame in the livedit-debugger.js just adds a throwing wrapper around it.
Also NEEDS_STEP_IN_PROPERTY_NAME was removed, the client code can decide based on the stack_modified field if "step in" is required.

This preserves the context-independent entry in an optimized code map
across GCs when the code is considered young (i.e. less than 3 ages).
Note that any context-dependent entry for the same code will still be
flushed immediately when the respective context dies, hence context
lifetime is not increased.

This allows the optimized code map to contain no context-dependent
entries, but still hold one context-independent entry. This is a
precursor to extending the lifetime of the context-independent entry.

This fixes a recent regression where the register holding the original
receiver was pushed onto the stack before the internal frame within the
CallStubInRecordCallTarget helper was created. That in turn confused
the stack walker when allocations in these stubs failed.

This fixes a recent regression where the register usually holding the

compiled for super calls (i.e. IsSuperConstructorCall). This led to
untagged values being present in the stack frame.

The background parser checks for debugger state in its constructor. This
is not good enough, since the debugger state may change afterwards, but
before compiling takes place. As the background parser can only parse
lazily, this could mean that due to debugging, we try to eagerly compile
an inner function we have not eagerly parsed.
