0ea3406b71 Add storeimm32 and storeimm64 syntax
These explicitly allow usage of storeimm32 and storeimm64 in the
assembler syntax. It will also warn you if you try to store a value
that's too large using the storeimm32 instruction

a4a37b5a27 Add Disassemble, fix bug in position calculation
* Disassemble structure can be used for dumping an object section
* Assembler position calculation was messing up, causing jump addresses
  to be wrong. This is fixed.

e198da5825 Finish up parser and assembler with more-or-less complete syntax
Major changes inlude:

* Bit the bullet and now instructions have their length hard-coded
* Move from_utf8 object parsing to be done by their objects (instead of
  a Parser god object)
* A list of AST sections are assembled into an Object using the new
  vm::obj::assemble module.
* Changed the object layout some in the spec, and adjusted code to match
  this.
