Continuing Quick compiler refactoring

With this CL, we no longer include any .cc files - all source
files compile stand-alone.   We still build a separate .so for
each target, but all code in the target-independent "codegen"
directory is now truly independent and doesn't rely on any
target-specific macros to compile.

Header file inclusion is still a bit of a mess, but that will be
addressed in a subsequent CL.

Next up: create a codegen class to hold code generator routines
overrideable by target.
