With bytecode flushing and lazy feedback allocation, we need to call
%PrepareForOptimization before we call %OptimizeFunctionOnNextCall

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.

Native context specialization now lowers monomorphic and
polymorphic accesses to data and constant data properties on
object and/or prototype chain. We don't deal with accessors
yet, and we also completely ignore proxies (which is compatible
with what Crankshaft does).
The code is more or less the straightforward implementation. We
will need to refactor that and extract common patterns once the
remaining bits for full load/store support is in.

Reason for revert:
Waterfall redness.

This patch strengthens testing of classes by verifying that the binding
that they export externally follows block scoping, as opposed to var-style
scoping. The tests are based on existing tests for let and const.
