- Default constructor scopes won't need the scope data for deciding the scope
allocation of variables inside them. Also, PreParser doesn't construct them. So
they should be just skipped when applying the scope data.
- PreParser needs to declare the class name + have a proper end position for
the class scope.
- This makes all mjsunit tests pass with --experimental-preparser-scope-analysis.
- Also added several DCHECKs which were useful for debugging.

Crankshaft flag and opt flag mostly serve the same purpose. Using
crankshaft to mean use optimizing compiler is a bit confusing.
This cl: https://chromium-review.googlesource.com/c/490206/ fixes
the tests to use opt instead of crankshaft flag.
One difference between --no-crankshaft and --no-opt would be that
--no-opt would mean no optimizations at all where as with --no-crankshaft
would mean we can force optimizations using %OptimizeFunctionOnNextCall.

For small arrays, it's way faster to just move the elements instead of
doing the fairly complex and heavy-weight left-trimming. Crankshaft has
had this optimization for small arrays already; this CL more or less
ports this functionality to TurboFan, which yields a 4x speed-up when
using shift on small arrays (with up to 16 elements).

where it's asked perform impossible operations, like loading a tagged

This patch expands scope analysis to skip hole initialization
when it can be determined statically that no hole checks will
be generated at runtime.
Two conditions must be met to safely eliminate hole initialization:
- There must not exist a VariableProxy referencing this Variable
whose HoleCheckMode is kRequired
- The Variable must be stack allocated; any other allocation implies
that it may be accessed from not-yet-analyzed scopes (other modules,
inner functions, or eval code) and that code may require
hole checks.
The new logic required removing debug code in full-codegen which is
now incorrect in some cases.
Also fixed Variable's bitfield helpers to take no more space than needed.
