- 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.

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.

Removes the do-expression wrapping, modifies BytecodeGenerator change
to enter a class literal's block scope if needed.
This does not solve the actual bug in v8:6322, but helps mitigate it in
simple cases. The bug is caused by BytecodeGenerator not allocating a
large enough array of context registers to hold its entire stack,
allowing non-context registers to be overwritten during PushContext and
PopContext bytecodes.
Nevertheless, I like the idea of not depending on do-expressions when
possible, so I think it's worth doing anyways.

Executing the |end| opcode of a loop assumed that the stack height was
being reset to the height at start of the loop. Hence we were ignoring
the arity of the loop.
During computation of the side table, the arity of the label associated
with the loop was explicitly set to 0, such that a |br| instruction to
that label would not transfer any values.
It turns out though that we need to remember the arity in order to
precompute the correct stack height when executing the |end| opcode of
