45ff9d53c5 [turbofan] Optimize remainder of integer division by unknown power of two. 
Drive-by-Fix: minint % 0 was broken on ARM, but we didn't notice because
there was no test covering that case...

6e148989a4 [turbofan] Smartify the GraphReducer. 
Don't use the generic algorithm, but instead start going into the
direction of ControlReducer, using a stack plus a revisit queue to
not miss any more possibilities for reductions anymore.

2e38f33911 Revert "TransitionArray now uses <is_data_property, name, attributes> tuple as a key, which allows to have several entries for the same property name." 
Revert "Fix for an assertion failure in Map::FindTransitionToField(...). Appeared after r25136."

This revert is made in order to revert r25099 which potentially causes renderer hangs.

aa6815c79a Classes: Add support for arguments in default constructor 
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.

3b3929fdc7 Reland "Avoid some unnecessary fast-properties map creations." 
This relands commit ea74f0f85a.

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.

f133ac501b In-object double fields unboxing (for 64-bit only).
