Initial copy elision pass (#8042)
Fixes #7574
Changes:
* Add an initial (fairly simple) optimization pass which is able to
eliminate redundant copies.
* Our current existing optimizer passes remove redundant load/store very
robustly, this pass will focus on other cases of copy elimination
* Primary approach is to make all functions which are `in T` and `T` is
trivial to copy into a `__constref T`. We then (depending on scenario)
manually insert a variable+load if a pass-by-reference is not possible;
otherwise we pass by `constref`.
* Added optimizations to eliminate redundant code which causes
`constref` to fail to compile
