Add a simple tuple optimization pass (#5937)
In some cases tuples are obviously not needed, such as when they are only used
in local operations and make/extract. Such tuples are not used as return values or
in control flow structures, so we might as well lower them to individual locals per
lane, which other passes can optimize a lot better.
I believe LLVM does the same with its own tuples: it lowers them as much as
possible, leaving only necessary ones.
Fixes #5923
