Unifies the global and unallocated variable type accesses given that
--global_var_shortcuts is going away. Lda/StaGlobal is modified to use
Load/StoreICs on the global object. The named LoadIC and StoreIC bytecodes
are also modified so that they take a constant pool entry index for the
name rather than a register, avoiding unecessary LdaConstant bytecodes to
be emitted.

Adds support for local context loads and stores. Also adds support for
creation of new block contexts (e.g., for let variables) and initializing
const / let variables with the hole appropriately.
Also adds some checks to ensure BytecodeArrayBuilder::context_count is set
appropriately and fixes tests to do so.
Adds the bytecode StaContextSlot.

Adds support for strict mode load / store ICs and cleans up BinaryOp and
CompareOp to only trigger an UNIMPLEMENTED abort if called with STRONG
mode (which is the only language mode which has different compare/binary ops.

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
and groups all the interpreter builtins together.

Reason for revert:
Now breaking arm32 debug bot (worked locally even with --debug-code, so I'll need to figure out what's different on the bot)

Reason for revert:
Broke Arm64 bot (CEntry stub is trying to pop arguments off stack when argv_in_reg, so I need to fix this).

Adds support for short operands, starting with kIdx16. Introduces
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.
BytecodeTraits template magic inspired by oth@chromium.org.
