In the process, add the bint type (which stands for Best-INTeger),
which implements Torque's idea of CSA's ParameterMode. It maps to
a different type on 32-bit (Smi) and 64-bit (intptr). There are
convert operators that are either no-ops or conversions
to-and-from Smi and intptrs on the each platform, depending on
the underlying type for bint. This allows Torque code to git most
of the benefits of ParameterMode without having to explicitly
pass around the mode, since it is almost always OptimalMode anyways.

Enable --harmony-string-matchall by default.

String.prototype.matchAll behaves similarly to
String.prototype.match, but returns a full regexp
result object for each match in a global or sticky
regexp. This offers a simple way to iterate over
matches when access to e.g. capture groups is
needed.

const string = 'a b c';
const regex = /[ac]/g;
for (const match of string.matchAll(regex)) {
  console.log(`${match[0]} at ${match.index}`);
}
// a at 0
// c at 4

More information can be found here:
https://github.com/tc39/proposal-string-matchall

Drive-by: Update debug evaluate side effect
expectations to handle String.p.matchAll and
RegExp.p[@@matchAll]

Remove a DCHECK that got triggered in the rare condition that GC kicks in
during CompilationDependencies::Commit, changing the pretenuring decision,
thus leading to deoptimization. To make sure this rare case is properly
handled, add a new FLAG_pretenure_during_compilation and a cctest that
simulates it predictably.

Now, we also print the fixed ranges, which are used to model fixed
register constraints.

The new ObjectPtr design makes non-inlined helper functions a little
more expensive because "this" is always a pointer where pass-by-value
would be more efficient, which is an issue for functions whose size puts
them right at the threshold of getting inlined or not. String::Get falls
into this category when called from RegExpFlagsFromString. In this case,
we can do even better than restoring inlineability by fine-tuning
the control flow a bit.

This should repair the regression in crbug.com/910573
