5e2c23e2d3 [destructuring] Get non-coercible message contents in runtime
For desrtucturing assignments from null/undefined, we throw an error
that references the destructuring object literal's property name, e.g.
for
  var { x } = null;
we report that we cannot destructure 'x' from null.

Rather than calculating this property during bytecode generation (and
including it in the bytecode as an argument to the type error
constructor), we can calculate it at exception throwing time, by
re-parsing the source in a similar way to the existing call site
rendering.

This slightly decreases bytecode size and slightly decreases the amount
of work the bytecode compiler needs to do. In the future, it could also
allow us to give more detailed error messages, as we now have access to
the entire AST and are on the slow path anyway.

9365d0904e [coverage] Rework continuation counter handling
This changes a few bits about how continuation counters are handled.

It introduces a new mechanism that allows removal of a continuation
range after it has been created. If coverage is enabled, we run a first
post-processing pass on the AST immediately after parsing, which
removes problematic continuation ranges in two situations:

1. nested continuation counters - only the outermost stays alive.
2. trailing continuation counters within a block-like structure are
   removed if the containing structure itself has a continuation.

76cb4fe626 [esnext] Ship String.p.matchAll/RegExp.p.[@@matchAll]
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]

4ab8c906e1 [Cleanup] String::GetChars() should take a DisallowHeapAllocation ref.
Building on https://chromium-review.googlesource.com/c/v8/v8/+/1349243,
which asserted on calls to GetChars() that weren't in a
DisallowHeapAllocation scope, this CL takes a reference to the scope
in order to provide static protection in all builds.

10ea3f8a1d [Compiler] Introduce IsCompiledScope which prevents flushing of compiled code
Introduces a IsCompiledScope object which can be used to check whether a
function is compiled, and ensure it remains compiled for the lifetime
of the scope without being uncompiled by bytecode flushing. The Compile
functions are modified to take a scope so that calling code can ensure
the function remains compiled for the lifetime they require.

Also, don't allocate a feedback vector for asm-wasm code as this
is never used, and will be reallocated if the asm-wasm code fails to
instantiate the module and we fallback to regular JavaScript.

Also restructure Compiler::PostInstantiation() to allocate the feedback
vector once, and do the optimized code check before optimizing for
always opt.

6292fdb84e [Debug] Special case DebugBreakOnBytecode for cases where we restart the frame.
When restarting a frame on returning from a debug break, we are going
to drop the current function frame, therefore the return value and
next bytecode are not going to be used. Special case these situations
since with bytecode flushing it is possible the SFI for the
executing function might have been flushed (if edited by liveedit)
which causes failures when trying to read from the bytecode array.

6c3d784c16 Rename fields to names or members
Rename variables and flag names so that the classes can be reused
by private methods implementation.

In particular:

Rename "fields" to "members" in the initializer so that we can
initialize both fields and private methods/accessors there,
for example:

instance_fields_initializer -> instance_members_initializer
InitializeClassFieldsStatement -> InitializeClassMembersStatement

Rename "private field" to "private name" for the private symbols
used to implement private fields so that we can use them to
store private methods/accessors later as well, for example:

private_field_name_var -> private_name_var
NewPrivateFieldSymbol -> NewPrivateNameSymbol

The follow-on is in
https://chromium-review.googlesource.com/c/v8/v8/+/1301018

https://docs.google.com/document/d/1T-Ql6HOIH2U_8YjWkwK2rTfywwb7b3Qe8d3jkz72KwA/edit?usp=sharing
