Don't allocate feedback vectors and feedback metadata in lite mode. Also updates to skip tests that require feedback vectors.

This addresses most of the regression in of Kraken's json-stringify-tinderbox-orig with 31bit Smis: Many object properties become heap numbers, and printing an integer which is represented as a double is slower than printing the integer directly.

We don't eagerly throw for assignments to calls; see v8:4480. They are simply turned into assignments to Property instead. We need to record a declaration error, however. Otherwise we'll end up with a Property in a declaration context. To reduce the scope of the lazy throwing, in this fix I record a pattern error instead, making calls as assignment target in a destructuring assignment context throw eagerly.

This CL moves variables that control MicrotaskQueue to MtQ itself. Namely, * is_running_microtasks_ and microtask_completed_callbacks_ from v8::internal::Isolate * microtasks_depth_, microtasks_suppressions_ and debug_microtask_depth_ from v8::internal::HandleScopeImplementer. As the current implementation has these variables one per-Isolate rather than per-MicrotaskQueue, this is needed to have multiple MicrotaskQueues for an Isolate.

The function InstanceBuilder::ProcessImports got long and hard to understand. This CL is the third change of a series which aims at extracting parts of ProcessImports into specialized functions. This CL extracts the processing of imported globals into a separate function. Aside from copying the code, I made the following changes: * Rename {index} to {import_index}. This CL does minimal changes to the processing of globals itself. That code looks quite complex at the moment. Therefore I want to do the refactoring of that code in separate CLs, so that each CL is smaller and more understandable.

On MIPS and MIPS64, UseScratchRegisterScope has only one register for the scratch register [1,2], and TurboAssembler::CallCFunctionHelper runs out of it as fast_c_call_caller_fp_address uses the register. That causes code generation failures. As a workaround, this CL reduces the number of nested UseScratchRegisterScope where the code generation is failing.

When we call ObjectToString on JSValues we only looked at string tags on the prototype map of the JSValue's value type and do not check the tags on the JSValue's prototype chain which may be non-trivial if subclassing is involved. For ex: if we have a class Test extend Number, we only looked for tags on the Number prototype and not on the Test prototype. This cl fixes the builtin to also check for these cases.
