This is currently done by generating a default constructor that looks
like this:

  constructor() {
    %DefaultConstructorSuperCall();
  }

The a runtime function implements the logic which is pretty similar to
Runtime_Apply except that it uses the [[Prototype]] of the current
function.

This is the second try. The first failed because the test was using a
array that was too large for Function.prototype.apply.

Revert "Revert "Classes: Add support for arguments in default constructor""

This reverts commit 43aa7e541df56a132608b8b4217e9da84575e4f8.

FunctionLiteral has two purposes: it is a unit of compilation, and it is
also an expression.  Its id() is only for the latter purpose, used by
the continuation of the closure, not by the closure itself.

When we inline, we treat the FunctionLiteral as a unit of compilation,
not as an expression, and as such the FunctionLiteral doesn't have any
meaningful ID.  The right thing to do is not to access the ID when
printing the hydrogen expression.

This relands commit ea74f0f8.

The revert was due to failures in cctest/test-heap/ReleaseOverReservedPages,
caused by apparent changes to memory layout and fragmentation of the
first page. Eliminating a situation in messages.js where this CL has had
an effect on map transitions seems to solve the issue.

1) It's unused. 2) Since Zones can be used on a background thread, the Zone
cannot just access this counter from the Isolate, so keeping this counter up to
date would require extra work. Better to just remove it.

Lowering of NumberToUint32 and NumberToInt32 was not correctly accounting for the sign of the input and the sign of the output, emitting the wrong representation changes.

Along the way, I've found cases where MachineOperatorBuilder would break if fed a machine type for loads or stores that was not cached, requiring MachineOperatorBuilder to take zone to allocate operators for these cases.
