This change adds support for local control flow when building graphs
from bytecode. The change ensures loop emitted from the bytecode
generator are in natural order so the only back branches are for loops.

Adds implementation and tests for CreateObjectLiteral, CreateArrayLiteral and CreateRegExpLiteral
to bytecode graph builder. Also changes these bytecodes to expect three operands instead of using
accumulator to pass one of the operands. This is done to avoid looking into the earlier nodes to
fetch operands in the bytecode graph builder. Also adds support for wide variant of these
bytecodes to bytecode generator and bytecode graph builder.

an optomization to remove redundant cast operations.
1. Adds an optimization to remove redundant ToBoolean and ToName operations.
2. Adds implementation and tests for cast operatorts to bytecode graph builder.

Previously all contexts had a link to the global object, but what is
required in most cases (except for the global load, store and delete
case) is the native context.
This also removes the second dummy global object that was still linked
to every native context. We will add a different mechanism to ensure
that builtins do not pollute the actual global object during
bootstrapping.
Drive-by-fix: Unify some MacroAssembler magic and drop obsolete stuff.

Adds support for visiting the Call bytecode to the bytecode graph builder.
This change also adds the call type feedback slot to the Call bytecode.
This is not currently used by the interpreter, but is used by the
graph builder.
Also adds a CallWide varient of the Call bytecode, and adds the kCount16
operand type.

Adds implementation and tests for following operators in bytecode graph builder:
-VisitLoadICSloppy
-VisitLoadICStrict
-VisitLoadICSloppyWide
-VisitLoadICStrictWide
The current implementation introduces empty frame states for frame state inputs expected by these operations.
