Refactor the JIT to be object-oriented (#1879)

Browse Source 
* Move TinyVector to a new file

- So it's less sensitive to #include ordering

* Forgot to include assert.h

* Refactor ARMJIT_Memory into an object

* Oops, forgot a declaration

* Refactor ARMJIT to be contained in an object

* Remove an unused function declaration

* Add a missing #include

* Remove a now-unused global

* Use ARMJIT_Memory's own memory access functions

* Fix some omissions in the ARM JIT

* Move libandroid to be a member of ARMJIT_Memory instead of a global

* Default-initialize most fields in ARMJIT_Compiler.h

* Define NOOP_IF_NO_JIT

* Finish refactoring the JIT to be object-oriented
