This CL introduces a ProtectedLoad instruction with is needed for out of bounds trap handling. ProtectedLoad behaves like a regular load, but it takes a context and source position parameter as well. These are used by an out of line code fragment to generate code to throw a JS exception for an out of bounds memory reference in Wasm. These changes a cleaned up subset of https://codereview.chromium.org/2148743004/ The rest of this feature will follow in future CLs. This includes a table mapping memory instructions to landing pads as well as the actual signal handler.
