This CL is part of a series that implements Turbofan support for
property accesses satisfying the following conditions:
1. The holder is a dictionary mode object.
2. The holder is a prototype.
3. The access is a load.
This feature will only be enabled if the build flag
v8_dict_property_const_tracking is set.
This particular CL modifies existing mjsunit tests whose assumptions
don't hold if v8_dict_property_const_tracking is enabled. This is
done by adding special handling for the case that
%IsDictPropertyConstTrackingEnabled() holds.

This is in preparation to the removal of the FullCodeGenerator, we no
longer need the ability to stress the underlying implementation.

This makes the runtime rely on the {HasBytecodeArray} predicate to
determine whether code generated by TurboFan was build without any
deoptimization support, as opposed to {asm_function}.

1. Replaces --crankshaft with --opt in tests.
2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.

This CL adds --crankshaft and --no-always-opt flags to the tests that use
assertOptimized() and assertUnoptimized() respectively.
This CL also adds presubmit checks that ensure that tests have the proper
flags set.

The mentioned asserts did not work properly with interpreted and turbofanned functions.
To fix this issue %GetOptimizationStatus() now returns a set of flags instead of a single value.
This CL also adds more helper functions to mjsunit, like isNeverOptimize(), isAlwaysOptimize(),
isOptimized(fun), etc.
