* Reduce buffer size, because 100 is plenty. (usual len is <10)

If we specialize OSR-only phis to `MIRType::Value` during conversion, then it is possible for `adjustPhiInputs` to see a phi that is still `MIRType::None`. On x86, this ends up with us crashing while trying to box a Value.
It's more robust to do a separate pass at the end of phi specialization, before we start converting.

At the same time, the initialization and storage of private methods is changed
to what the PrivateOpEmitter expects.
There are some barely-observable differences in behavior, resulting in two jit-test changes:
* fields/bug1683784.js - An error message changed. Not really better or worse.
* js/src/jit-test/tests/parser/script-source-extent.js - The debugger is able
to observe initializers as individual scripts. We are no longer using
initializers for private methods that can be optimized, and the debugger
therefore observes the change. I adjusted the test to expect the new
behavior.
All js/src/tests pass.

The diff is a mess, but this is very straightforward--we have a combination of
if-statements and a switch that could just be a single switch.

Differential Revision: https://phabricator.services.mozilla.com/D108296
In order to correctly support this with the optimized storage for methods we
would need new bytecode like GetAliasedVar which is able to traverse
non-EnvironmentObject environments like DebugEnvironmentProxy.
Unfortunately, for safety this means we will ultimately disable this for a number of
different private field and accessor invocations.

By storing NameLocations we also get a BindingKind, which allows us to disambiguate between
PrivateMethods and Synthetics.
Differential Revision: https://phabricator.services.mozilla.com/D109401
This would cause private methods to be marked as such on scopes, except that
the parser still declares them as `DeclarationKind::Synthetic` for now.

This affects bytecode, as Synthetic bindings do not get TDZ checks.
This patch also tightens up some assertions when creating ScopeData. There are
several methods that create ScopeData, and they had gotten out of sync. The
assertions check that the ScopeData is not silently dropping bindings that were
present in ParseContext::Scope::declared_.

This is currently used only by the bindings in a ClassBodyScope.
The behavior of these bindings is like Var bindings. There is no longer a TDZ
check, and we don't bother marking them as Uninitialized. So the special case
introduced in bug 1683746, peeking at the binding name to see if we should skip
the TDZ check, is no longer needed.

This adds a hasPrivateBrand bit to the MemberInitializers struct in the
stencil. It is necessary to persist this bit across compilation units because
emitInitializeInstanceMembers can be called in direct eval code inside a
derived-class constructor.
Since .privateBrand is currently a `let` binding, this currently emits an
unnecessary CheckAliasedLexical instruction in the constructor for each class
that has nonstatic private methods. We'll eliminate these later on.

Differential Revision: https://phabricator.services.mozilla.com/D108290
Not every class gets this special binding. It will be needed for all classes
that have any nonstatic private methods, getters, or setters. With this patch,
we create a .privateBrand binding in the scopes for such classes, and populate
it with a symbol when initializing the class. However, it is not yet being used
anywhere; the constructor does not yet stamp instances with the private brand.

It is a copy of BlockLexicalEnvironmentObject. Note that
- ClassBodyScope is *not* a LexicalScope, BUT
- ClassBodyLexicalEnvironmentObject *is* a LexicalEnvironmentObject
This is strictly a matter of how much implementation is shared. The word
"Lexical" in LexicalEnvironmentObject, and to some extent throughout
SpiderMonkey, is alas already pretty meaningless. In the language
specification, all environments are lexical environments.
