replacing the current [[accumulate]] implementation: shorter and simpler, and also supports non-void return types

Ignore generating a return instruction in accumulated functions, eventually we'll have a way to merge these into one function but for now the RETURN is a waste.

Fix some things: get all the Quake mods to compile again (I broke binary expressions .. oops) Fix the check-proj script, using $? for status was invalid because of pipes. The ir now properly considers negation virtual instruction to be operations (as it should).

Make unary - operator act as an ast_unary node. This allows for consistency (no sense in making unary use binstore nodes, it doesn't make much sense). It also allows for the peephole optimization on unary chains that cancel each other to take place; i.e code like "-(-a)" simplifies to "a", thus eliminating instructions.

Implement [[eraseable]] attribute. When used with a function it instructs the AST (which than transfers logic to the IR) that the function (or variable) is potentially unused (verified by checking the read count). This than propogates through the IR and prevents the IR from generating both the definition and global/function. The intrinsics system uses this as well to prevent intrinsic functions from being generated unless they're used.

Constant fold intrinsics if their arguments are constant. TODO: reference count intrinsics such that they're not generated unless they're used, currently when an intrinsic can be folded-away it's marked for generation and makes it to the final output binary even though it isn't used.

Major header reworking, this respects the namespaces properly. Makes object dependency more obvious, allows for better make caches, and prevents misuse of library features, i.e use con_* instead of printf.

Experimental support for implicit return assignments. This closes #107. To enable return assignment support use -freturn-assignments. This allows you to do the following in QC code. T name() { return = expr_eval_T; return; /* returns expr_eval_T */ }. It allows for concise code and to rid locals in functions. It also saves a tremendous amount of space since only types of certian globals need to be allocated for returns.

Major export cleanup. Anything that was exported but wasn't used outside where it was implemented has been turned into static, and their exports have been removed. This actually makes the compiler compile slightly faster.
