zig ir.cpp details: remove the mem_slot mechanism

Previously, there was hacky code to deal with result locations and how they work with regards to comptime values and runtime values. In addition, there was a hacky "mem_slot" mechanism that managed the memory for local variables, and acted differently depending on comptime vs runtime situations. All that is deleted in this commit, and as a result, result locations code has one less complication. Importantly, this means that a comptime result location is now passed to a function when it is evaluated at comptime. This test causes many regressions, and some of the behavior tests are disabled (commented out) in this commit. Future commits will re-enable the tests before merging the branch.
