8854589c79 Revert "Correct semantics for numerically indexed stores to typed arrays." 
This reverts commit r24691 because win64 release build breaks.

e4c6f9488e Implement graph trimming in ControlReducer. 
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.

This CL is one half of the ControlReducer functionality, the other half
being branch folding.

d8ae78539f X87: Eliminate special keyed load string stub in favor of uniform handlers 
port r24661.

original commit message:

  Eliminate special keyed load string stub in favor of uniform handlers.

  KeyedLoadIC installs a special case if the receiver is a string.
  Although there are several maps for strings, in practice we seem to
  be able to treat them individually because a given KeyedLoad site
  only sees 1-2 string types

0841f7241b Track usage of "this" and "arguments" in Scope 
This adds flags in Scope to track wheter a Scope uses "this" and,
"arguments". The information is exposed via Scope::uses_this(),
and Scope::uses_arguments(), respectively. Flags for tracking
usage on any inner scope uses are available as well via
Scope::inner_uses_this(), and Scope::inner_uses_arguments().

Knowing whether scopes use "this" and "arguments" will be handy
to generate the code needed to capture their values when generating
the code for arrow functions.

15bc4aa2c8 [turbofan] Run value numbering after SimplifiedLowering. 
Running ValueNumberingReducer together with ChangeLowering causes

running it before we get to change lowering works around that well-known
(phase ordering) problem for now.
