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.

When a FunctionTemplate-based function is used as a constructor

This reduces the amount of special paths for testing.
Setup the memory used for testing exactly the same way as in real world.
Also, always connect the interpreter to the instance being executed,
and to the existing WasmInstance struct. This keeps information
synchronized between interpreter and test runner.
These changes allow us to execute e.g. GrowMemory from cctests either
in the interpreter or in compiled code.

When accessing JSArray::length property from GenericPropertyLoad
(i.e. via a megamorphic KEYED_LOAD_IC), we'd always go to the runtime
at this point, because the CallGetterIfAccessor method didn't support
AccessorInfos at all. Now there's initial support for JSArray::length,
which reduces the number of %KeyedGetProperty calls we see in the
Speedometer/EmberJS test by 5000.
