  2. Update fmt and use of memcpy 

    I'm still not totally sure if this is the right way to implement the memcpy, but that portion
compiles correctly now. Now to fix the compile errors everywhere else :).

  3. Update match branches 

    This updates all places where match branches check on StatementKind or UseContext.
This doesn't properly implement them, but adds TODOs where they are, and also adds some best
guesses to what they should be in some cases.

  6. Replace todos with impls 

    Changed to various implementations, copying the style of prior function calls in places I was
unsure of.

Also one minor style nit.

  7. Change CopyNonOverlapping::codegen_ssa 

    Fixes copy_non_overlapping codegen_ssa to properly handle pointees,
and use bytes instead of elem count

  8. Build StKind::CopyOverlapping 

    This replaces where it was previously being constructed in intrinsics, with direct construction
of the Statement.

  9. Switch to changing cp_non_overlap in tform 

    It was suggested to lower this in MIR instead of ssa, so do that instead.
