This completes the transition to Assembler::Options, which reduces the assemblers's dependency on isolates, and there is now only one way to create an Assembler, which is to use the options. Note that some operations on assemblers still need an isolate, such as GetCode(), and in these cases, the isolate is an additional argument to the method.
