Use Literal String pcre optimization for more pcre functions

Summary:
Currently, the pcre literal string optimization is only used for preg_match. Lets extend it to the other pcre functions as well.

This will allow us to skip compiling the regex at all when we use literal_data to match instead.

str purity: starts_with/ends_with

Summary:
We currently use substr_compare; instead of directly porting it, I'm special-casing these:

- these are the only things we're actually doing in the HSL
- equivalence can be better optimized than comparison
- it's better to do UTF16 conversions once then operate efficiently there than to chain together
  other operations in multiple encodings

Introduce StringishObject, Have HHVM magically generate StringishObje…

…ct instead of Stringish on objects

Summary:
As part of a way to give a roadmap for folks who are using deprecated replacements for old-style stringish_cast to replace that with reasonable code.

The idea being that they have a stringish object, they can test against this type and then safely invoke the method vs Stringish::__toString which might actually try to invoke a method on a string.
