ced4183158 More restructuring of arch/ and os/ code. 2014-08-18 16:54:01 +00:00

3e8ba50851 Add common arch/ folder, move headers out of os/. 
Much of the architecture-specific code uses compiler-agnostic
intrinsics. For this reason, split it out into an arch/ folder,
leaving only the compiler and environment-specific code in os/.

bf46aa1fb3 Reorganize structures. 
If we place larger, less commonly used structures after our
frequently accessed state variables, the average size of x86
instructions will be reduced due to the smaller offsets off
the base pointer.
