b0ef49bc2a Add assembler and execution logic
Most everything works, but there's one small bug with the execution
involving jumps - still have to figure that one out.

cf9ba376aa Add value directives and strings
.string, .zstring, .u64, .u32, .u16, .u8 are used before an ImmValue to
determine how the memory should be laid out for that value.

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

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.
