8f336b3970 revert one part of ir get_elem_ptr analysis 
this reverts one part of 4c3bfeca. it solves some behavior regressions
but introduces new ones. This change was incorrect to make however,
and this commit takes the code in a better direction.

fbcee58cfc 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.
