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. BUG=v8:4280 LOG=N Review URL: https://codereview.chromium.org/1370893002 Cr-Commit-Position: refs/heads/master@{#31058}
