12ba2dd435 Improve dead phi elimination. 
This change splits the existing phi elimination into two phases:
1. Remove redundant phis
2. Remove dead phis with a fixed point iteration.

The new approach allows us to remove dead phis that are connected
in a cycle.

927f341d3c Strict mode arguments do not share binding with formal parameters. 
Move strict mode flag from TemporaryScope to Scope so that it can be accessed from variable binding code.
Arguments do not alias in strict mode (ia32, x64 and arm, codegen and full codegen).
Hydrogen tolerates null arguments_shadow().
In codegen-<arch> arguments object is allocated eagerly to capture values before they get modified.

c3172a6b7e Refactor polymorphic load and inline function graph construction. 
Change the way we construct the graph for polymorphic loads to match that of
polymorphic stores.

Introduce a stack-allocated helper for saving and restoring all the
function-specific graph builder state that needs to change when we begin
translating an inlined function.  Make this class authoritative by moving
redundant state out of the builder and deferring to the current function's
state.

Ensure that we always print a tracing message when abandoning an inlining
attempt.

4707d7ac08 Stop using plain Arrays internally in built-in functions. 
In built-in code we use arrays for internal computations.
This makes it possible to affect the built-in code by putting getters
or setters on the Array prototype chain.
This adds a new internal Array constructor that creates Arrays with
a very simplistic prototype chain that doesn't include any publicly
visible objects. These Arrays shoudl ofcourse never leak outside the
builtins, since that would expose the prototype object.
The prototype object contains only the array functions that we use:
push, pop and join (and not even a toString, so it doesn't stringify
well).

Also change uses of .call to %_CallFunction.

SetElement can cause an exception to be thrown. If its return value
isn't checked, this exception might not be handled at the correct time.
In some cases, it's a matter of returning Exception::Failure() from
a runtime function.
In other cases, code using SetElement on a JSArray has been changed
to setting directly on a FixedArray and only creating the JSArray
at the end.

Do not use subgraphs to implement the translation of simple branching

Combine all the loop construction functions into a single one.

Resolve a possible problem with duplicate AST IDs used both for joined loop
break blocks, the normal loop exit, and for their common successor, by never
introducing the extra (successor) block and instead making the normal loop
