f0d41c3fd6 [spv-out] Track block termination statically. 
Rather than giving `Block` an optional `terminator` field in addition to its
`body`, track block termination statically, with two types:

- `Block` is a block without a termination instruction. This is what most code
  generation functions operate on.

- `TerminatedBlock` is a block with a termination instruction. This is what
  `Function::blocks` holds.

The `Function::consume` method takes a `Block` by value, together with a
termination instruction, and turns it into a `TerminatedBlock`.

This lets us remove some unwraps and awkward conditions.

As part of this change, `Writer::write_block` no longer hits an `unimplemented!`
for Naga statements following `Break`, `Return`, and so on. Instead, it simply
doesn't emit code for them, which is a correct translation. If we want to forbid
these, we should handle that in validation instead.

548cde4701 Clear Validator::valid_expression_list before validating each function. 
If validation fails, `Validator` may be left with entries in
`valid_expression_list` and `valid_expression_set`. The validator does clear the
set before examining a function's body, but not the list, which means a
long-lived `Validator` could accumulate an unbounded amount of garbage in the
list.

(Minor cleanup: use structural update syntax where appropriate.)

a7cacab276 [spv-out] Move Writer type to back/spv/mod.rs. 
The `impl` blocks for `Writer` and its associated types remain in spv/writer.rs.

There should be no substantive code changes in this commit, only moving code
around and adjusting `use` declarations to match.
