Adds support for creation of new local function contexts (or script context for
top-level code). As part of this, also adds support for context push/pop
operations using a ContextScope object in BytecodeGenerator. Adds the following
bytecodes:
- PushContext
- PopContext
Support for inner contexts and loading from / storing to context allocated
variables will come in a future CL.

Adds support for calling runtime functions from the interpreter. Adds the
CallRuntime bytecode which takes a Runtime::FunctionId of the function to call
and the arguments in sequential registers. Adds a InterpreterCEntry builtin
to enable the interpreter to enter C++ code based on the functionId.
Also renames Builtin::PushArgsAndCall to Builtin::InterpreterPushArgsAndCall

BytecodeTraits to enable compile time determination of various traits for a
bytecode, such as size, operands, etc. Reworks BytecodeIterator,
BytecodeArrayBuilder and Bytecodes::Decode to support 16 bit operands. Adds
support to Interpreter to load 16 bit operands.
Also fixes a bug with ToBoolean where it wouldn't get emitted at the start
of a block, and added a test.

Adds LdaGlobal bytecode and augments BytecodeGenerator to load globals for
global variables and function calls.
Modified TestBytecodeGenerator to add the ability to specify that a bytecode
operand has an unknown value (used so we don't need to figure out the slot
index of a global). Also added a helper which checks equality of BytecodeArray
with the expected snipptets.
Modified TestInterpreter to allow it to take snippets of JS and have the
BytecodeGenerator generate the bytecode rather than having to build a
BytecodeArray manually. This is used to enable the global tests.
