Changes SharedFunctionInfo to store a function_token_offset, relative to the start_position, instead of the full function_token_position. This enables us to reduce both FunctionTokenPosition and ExpectedNofProperties to 16 bits each, saving 32 bits per SFI.

Without --harmony-function-tostring, anything other than a JSFunction or JSBoundFunction throw when Function.prototype.toString is called on them. But with the toString revision, anything callable allows toString (and for non-Functions returns the good old "function () { [native code] }" string).

For functions declared in source code, the .toString() representation will be an excerpt of the source code. * For functions declared with the "function" keyword, the excerpt starts at the "function" or "async" keyword and ends at the final "}". The previous behavior would start the excerpt at the "(" of the parameter list, and prepend a canonical `"function " + name` or similar, which would discard comments and formatting surrounding the function's name. Anonymous functions declared as function expressions no longer get the name "anonymous" in their toString representation. * For methods, the excerpt starts at the "get", "set", "*" (for generator methods), or property name, whichever comes first. Previously, the toString representation for methods would use a canonical prefix before the "(" of the parameter list. Note that any "static" keyword is omitted. * For arrow functions and class declarations, the excerpt is unchanged. For functions created with the Function, GeneratorFunction, or AsyncFunction constructors: * The string separating the parameter text and body text is now "\n) {\n", where previously it was "\n/*``*/) {\n" or ") {\n". * At one point, newline normalization was required by the spec here, but that was removed from the spec, and so this CL does not do it. Included in this CL is a fix for CreateDynamicFunction parsing. ')' and '`' characters in the parameter string are no longer disallowed, and Function("a=function(", "}){") is no longer allowed.
