Support for 64 bit integer types (#1191)

* * For integer literals add postfix, and use unsigned/signed output appropriately
* Extend GLSL extension handling by type, and for adding 64 bit int extensions
* Added tests for int/uint64 types

* Add explicit Int/UInt64 emit functions to avoid ambiguity.
