Represent all sliceable lvalues with LValueSlice class.
This encompasses fixed-index expressions, field-accesses, and now,
simple swizzles as well. The final code generation is the same as
before because we fuse adjacent stores as a peephole optimization,
but this will generate better code when we start using
`swizzle_copy_stack_to_slots` to store lvalues.
