Introduce THREADED_PROFILED_TEST macro

A bunch of tests in test-api.cc need to be executed two times: with CPU profiler on and off to check different code paths. There are only two such tests at the moment but I'm going to add more and having this logic duplicated in all these tests look awkward. The tests are executed as part of Threading* tests and there is no much sense in running CPU profiler in that case. This change addresses both problems by introducing THREADED_PROFILED_TEST macro which mosly resembles THREADED_TEST except that when such test is executed as a standalone test (not part of a test-api/Threading*) it will first run the test normally and the start CPU profiler and run the test again.

Reduce the amount of full code generated to fill out array literals.

This is achieved by tuning the calling convention of StoreArrayLiteralStub:

 * The map of the array literal can be loaded in the stub from the
   array literal itself, there is no need to pass it at all.

 * The array literal is already on the stack, so there is no need to
   pass it again via a register.

 * The literal index is unchanged while filling the literal, so we can
   push it on the stack once and avoid passing it every time. Note that
   we need to mirror this change in the stack layout in crankshaft, too.

This change modifies code produced by BaseLoadStubCompiler::GenerateLoadCallback so that instead of calling AccessorGetter direcly it calls InvokeAccessorGetter which changes VM state and calls the actual callback. This way CPU profiler knows which external callback is being executed in this case. Indirect call happens only if CpuProfiler::is_profiling() is true.
