d4b8622393 Rename the VOID type to INVALID and clean up obsolete comments. 
The VOID type isn't used for anything resembling what "void" means in C,
so rename it to INVALID to avoid confusion.

ca9da7702e Reorganize the global value kinds. (#490) 
* Reorganize the global value kinds.

This:
 - renames "deref" global values to "load" and gives it a offset that works
   like the "load" instructions' does
 - adds an explicit "iadd_imm" global value kind, which replaces the
   builtin iadd in "vmctx" and "deref" global values.
 - also renames "globalsym" to "symbol"

8e2d01a675 Add an index_type field to Table. 
This parallels the `index_type` field in `Heap`.

eb439c9a68 Fix legalization of heap_addrs with 32-bit indices. (#480) 
This makes several changes:
 - It adds an index_type to heap declarations, allowing heaps to specify the
   type for indexing. This also anticipates 64-bit heap support.

 - It adds a memory_type to deref global values, allowing deref globals to
   have types other than pointers. This is used to allow the bound variable
   in dynamic heaps to have type i32, to match the index type in heaps
   with i32 index type.

 - And, it fixes heap legalization to do the bounds check in the heap's
   index type.

6af407144c Remove Signature's argument_bytes field. 
It's not currently used. If we do need such information, it would be
better to compute it on demand.

76a7efc8db Clippy improvements (#408) 
* clippy: Allow subsec_nanos usage for now.

The recommendation from clippy requires Rust 1.27, but we currently

* Simplify ref pattern matches.

This was recommended by clippy.

26d122306d Don't attempt to shrink regfill/regspill/regmove instructions. 
This is a temporary workaround for bugs such as #420, where normal
operand constraint checking doesn't correctly handle such instructions.

other terms involving "language".

1b42105faa Remove reserved_reg functionality. (#424) 
* Remove reserved_reg functionality.

This wasn't implemented, and if we need it in the future, it seems like
it would be better to extend the concept of global values to cover this.

* Use GlobalValue::reserved_value() for sentinal values.
