Reason for revert: Speculative revert because it seems to introduce a pretty stable flake on gc stress tests, see https://bugs.chromium.org/p/v8/issues/detail?id=8229

Create LdaNamedPropertyNoFeedback and StaNamedPropertyNoFeedback

For a script '()=>42', the anonymous arrow function has both start and
end position the same as the script function itself. This causes issues
when sorting the SourcePositionEvents of the function, in two ways:
* If the start positions are the same, we should order by *furthest*
end position to ensure the stack is in the right order
* If both start and end are the same, we need to order by function
literal id to make sure that start order and end order are inversed.
Also, MapLiterals assumes that start+end position uniquely identifies a
function, which is false in this case, so we process the top-level
script function separately in MapLiterals.

Currently, we context allocate all parameters for generators.
With this CL, we keep arguments on stack (unless they escape to inner
closure) and copy them between the stack and the generator's register
file on suspend/resume. This will save context allocation in most cases.
Note: There is an asymmetry between suspend and resume.
- Suspend copies arguments and registers to the generator.
- Resume copies only the registers from the generator, the arguments
are copied by the ResumeGenerator trampoline.

There are likely cleanups that can be done after this CL:
- context-related functions in the interpreter and compiler take ScopeInfo as
well as ScopeType and slot-count as input. The latter 2 should be directly
derived from the former. We should be able to drop FunctionContextParameters.
- ContextExtension is probably not needed anymore, since we now always have the
correct scope_info directly in the SCOPE_INFO_INDEX slot.

Others are saved as optimized out constants, and are skipped during the

The catch prediction logic got confused when we merged the reactions and
result fields of JSPromise, because for settled promises it would start
to treat the result as reactions list, leading to a crash most likely or
memory corruption in the worst case (only if break on uncaught exception
is enabled). We can only inspect reactions when the promise is still in
"pending" state.

- All testcase/testsuite/variant generator subclasses renamed to
just TestCase/TestSuite/VariantGenerator since they're private
implementation.
- All `testcase` variables renamed to `test` to not conflict with
a module name.
- No more two statements in the same line.
- Removed some unused testsuite methods.

This is a reland of c3bd741efd
Original change's description:
> Fix "this" value in lazily-parsed module functions.
>
> When preparsing top-level functions in a module, we didn't track
> unresolved variables. Consequently, "this" ended up referencing
> the global "this", which has the wrong value (in a module "this"
> is supposed to be the undefined value).
>
> This patch fixes that. This also lets us stop forcing context
> allocation of all variables in module scopes, which the patch
> takes care of as well.
