ir::Value has a virtual Type() method. Implement this on the subclasses
that actually have a type.
Removed pointless memory usage on instructions that have no value.
Also un-getter some fields to match the other IR code.

There's a few reasons for this change:
* Not all values have identifiers, and carrying redundant fields is
inefficent.
* Not all IDs will be integers - much like LLVM IR and SPIR-V, we will
likely want to disassemble with textual identifiers, so a uint32_t
is not ideal, and a std::string is even more bloat for each value.
* Transforms don't use identifiers, but instead raw pointers. We don't
want to encourage using IDs as they're simply a less-efficient way to
refer to values.
* This makes values consistent with types and flow-control blocks, as
they will both have their disassembly ID generated by the
disassembler.
The next step will be to add a hashmap to the module so that
pre-declared value names can be stored out-of-band.

There's an odd mix of IR classes that use raw fields, and others that
have getters. Migrate a bunch of those getters to raw fields.

This CL removes the `ir::Runtime` and inherits `ir::Instruction` from
`ir::Value`. This means that any `Value` can be an `Instruction`. The
instruction id is used for debugging purposes.

This CL updates ir:Value to track the instructions which use a given
value. The instructions add their usage upon construction. This
necessitates making the values non-const in a lot of places as they get
changed by the instruction.
The `result` value is moved up to the base instruction class as it
should exist in all instructions.

The use of `operator<<` gets much more convoluted as things are changed
over to pointers and with inheritance. This CL switches the `operator<<`
methods to `ToString` functions.
