The address space and access mode both exist on the type of the Var,
storing the information into Var is redundant. This CL removes them from
var in favour of the type fields.

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.
