The `FAST_` prefix doesn’t make much sense — they’re all just different cases
with their own optimizations. Packedness being implicit (e.g. `FAST_ELEMENTS`
vs. `FAST_HOLEY_ELEMENTS`) is not ideal, either.
This patch renames the FAST elements kinds as follows:
- e.g. FAST_ELEMENTS => PACKED_ELEMENTS
- e.g. FAST_HOLEY_ELEMENTS => HOLEY_ELEMENTS
The following exceptions are left intact, for lack of a better name:
- FAST_SLOPPY_ARGUMENTS_ELEMENTS
- SLOW_SLOPPY_ARGUMENTS_ELEMENTS
- FAST_STRING_WRAPPER_ELEMENTS
- SLOW_STRING_WRAPPER_ELEMENTS
This makes it easier to reason about elements kinds, and less confusing to
explain how they’re used.

This removes the --turbo flag and solely relies on the filter pattern
provided via --turbo-filter when deciding whether to use TurboFan. Note
that disabling optimization wholesale can still be done with --no-opt,
which should be used in favor of --no-turbo everywhere.
Also note that this contains semantic changes to the TurboFan activation
criteria. We respect the filter pattern more stringently and no longer
activate TurboFan just because the source contains patterns forcing use
of Ignition via {AstNumberingVisitor::DisableFullCodegenAndCrankshaft}.

In current implementation in expressions like await foo() we have break location right after foo call and before actual await.
And we additionally have a lot of other statement locations because of do scope.
Let's move async debugging closer to sync debugging and introduce only one break location for await - before awaited function call.

Benefits (see test for details):

- removed redundant break location for expressions like: let { x, y } = { x: 1, y: 2}.

In particular, local variables should be allocated on stack (in bytecode register), and stored/loaded to the generator object on generator suspend/resume.
The CL is based on @adamk's change to scoping/parsers (https://chromium-review.googlesource.com/c/498538/), I only made the debugger cope with this change.
I should note that the CL changes the scope type of suspended generators from ScopeType.Closure to ScopeType.Local. In the future we might want to introduce ScopeType.SuspendedGenerator to make the distinction explicit.
Some of the changes in the tests have been made because the debugger functions do not return scopes of closed generators anymore. Generators should be allowed to throw away their internal state when they finish.

There are two break locations at the same source location by desugaring:
- call iterator.next,
- before variable assignment.
Additionally location for for..of loops is moved from before "of" to before each variable expression.
We should not report first implicit call to avoid user confusion. User still able to go into .next function with both scenarios:
- when this call is reached by stepOver or stepInto from previous line,
- when this call is reached because of breakpoint at current line.

This avoids emitting redundant {PopContext} bytecode instructions when
non-local control-flow leaves the method body. It also folds multiple
such {PopContext} instructions into one, in case several scoping levels
are crossed at one. Only the expected context of the target of a local
control-flow transfer matters.

3. Updates testrunner/local/variants.py and

let/const declarations in "standard" C-style for-loops have
some complex desugaring to accommodate the case where loop
loop variables may be captured. This slows down the baseline
performance of for-loops with let variables.
This change attempts to avoid this desugaring if it's known that
the loop variable is not captured at any point. A side effect of
this change is that let/const loop variables, when not captured
within the loop body, are not necessarily shown in the debugger,
similar to other stack-allocated vars.

This adds support for tracking token positions in the asm.js scanner and
uses these positions to emit a mapping from WASM to asm.js positions.
Note that the mapping is still incomplete (some call sites are not yet
covered).

We need to split creating of console and installing memory getter and remove console.assert hack before migration to builtin. We can implement super fast console.assert after migration.

Since we no longer support the ignition-staging configuration
any longer, we can retire the three tier pipeline and the
CompileBaseline functionallity.
We still need support for JSFunction self healing due to
liveedit (which for --no-turbo might end up replacing a
forced Ignition function with a FCG function) - we can
remove this once we remove --no-turbo support.

Proposed behaviour:
- StepNext at return position go into next function call (no changes with current behavior, but implemented in v8::Debug instead of hack on inspector side);
- StepOut at return position go into next non-current function call.
We need this to have better stepping in cases with native functions, blackboxed functions and/or different embedder calls (e.g. event listeners).
New behavior could be illustrated with two examples (for more see stepping-with-natives-and-frameworks test):
- let's assume that we've blackboxed callAll function, this function just takes its arguments and call one after another:
var foo = () => 1;
callAll(foo, foo, () => 2);
If we break inside of first call of function foo. Then on..
..StepNext - we're able to reach second call of function foo,
..StepOut - we're able to reach () => 2 call.
- let's consider case with native function:
[1,2,3].map(x => x * 2)
If we break inside of first callback call, then with StepNext we can iterate through all calls of callback, with StepOut we go to next statement after .map call.
Implementation details:
- when we request break we schedule step-in function call for any step action at return position and for step-in at any position,
- when we request StepOut at return position - we mark current function as needed-to-be-ignored inside of PrepareStepIn(function) call,
- when we request StepOut at not return position - we set break at return position and ask debugger to just repeat last step action on next stepping-related break.

String case conversion is known to debug-evaluate to not have a side
effect in noi18n mode, but debug-evaluate thinks it has a side effect
in i18n mode. Update the tests accordingly.
Verified locally that the test passes in i18n and noi18n mode (not sure
whether the noi18n trybot executes this test).
