Adds support for JS calls to the interpreter. In order to support
calls from the interpreter, the PushArgsAndCall builtin is added
which pushes a sequence of arguments onto the stack and calls
builtin::Call.
Adds the Call bytecode.

Adds support for property store operations via Store/KeyedStore ICs. Adds the
following bytecodes:
- StoreIC
- KeyedStoreIC
The --vector_store flag is now required for --ignition.

Adds support for property load operations via Load/KeyedLoad ICs. Adds the
following bytecodes:
- LoadIC
- KeyedLoadIC
Also adds support to the interpreter assembler for loading the type feedback
vector from the function on the stack, and calling ICs.

Adds support to the interpreter for loading literals from the constant pool.
Adds the LoadConstant bytecode and makes use of it for loading large Smis and
HeapObject literals.
Also removes unused HandleVector from utils.h.

Adds support for parameters to the BytecodeArrayBuilder and BytecodeGenerator.
Parameters are accessed as negative interpreter registers.

Adds implementations and tests for the following bytecodes:
- Add
- Sub
- Mul
- Div
- Mod
Also adds the Mod bytecode and adds support to BytecodeGenerator and
BytecodeArrayBuilder to enable it's use.
The current bytecodes always call through to the JS builtins. This also adds
LoadObjectField and CallJSBuiltin operators to the InterpreterAssembler.

Makes the following modifications to the interpreter builtins and
InterpreterAssembler:
- Adds an accumulator register and initializes it to undefined()
- Adds a register file pointer register and use it instead of FramePointer to
access registers
- Modifies builtin to support functions with 0 regiters in the register file
- Modifies builtin to Call rather than TailCall to first bytecode handler.

Modifies the BytecodeArrayBuilder to create register operands which are
negative. This reduces the number of instructions to access registers
by the interpreter and allows us to use positive register operands to
access parameter values.
Adds a Register class to keep register usage typesafe and simplify the
convertion to bytecode operand values.

Change minimum BytecodeArray frame size to zero now return value is in
the accumulator.
Fix inconsistent checks in bytecode-array-builder.cc.
Simplify bytecode disassembly by adding Bytecodes::Decode to
disassemble one bytecode and operands.

The BytecodeArrayBuilder has responsibility for emitting the BytecodeArray. It will be used by the AST walker.
Bytecode now uses an accumulator plus registers rather being pure register based.
Update BytecodeArray::Disassemble to print operand information.
