130c7fd23b self-hosted: working towards conditional branching test case 
New features:
 * Functions can have parameters in semantic analysis. Codegen
   is not implemented yet.
 * Support for i8, i16, i32, i64, u8, u16, u32, u64 primitive
   identifiers.
 * New ZIR instructions: arg, block, and breakvoid

Implementation details:

 * Move Module.Body to ir.Body
 * Scope.Block gains a parent field and an optional Label field
 * Fix bug in integer type equality comparison.

Here's the test case I'm working towards:

```
@void = primitive(void)
@i32 = primitive(i32)
@fnty = fntype([@i32, @i32], @void)

@0 = str("entry")
@1 = export(@0, "entry")

@entry = fn(@fnty, {
  %0 = arg(0)
  %1 = arg(1)
  %2 = add(%0, %1)
  %3 = int(7)
  %4 = block("if", {
    %neq = cmp(%2, neq, %3)
    %5 = condbr(%neq, {
      %6 = unreachable()
    }, {
      %7 = breakvoid("if")
    })
  })
  %11 = returnvoid()
})
```

$ ./zig-cache/bin/zig build-obj test.zir
test.zir:9:12: error: TODO implement function parameters for Arch.x86_64

That's where I left off.

5aa3f56773 self-hosted: fix test regressions 
I'm allowing incremental compilation of ZIR modules to be broken. This
is not a real use case of ZIR, and the feature requires a lot of code
duplication with incremental compilation of Zig AST (which works great).

d9c1d8fed3 self-hosted: improve handling of anonymous decls 
* anonymous decls have automatically generated names and symbols, and
   participate in the same memory management as named decls.
 * the Ref instruction is deleted
 * the DeclRef instruction now takes a `[]const u8` and DeclRefStr takes
   an arbitrary string instruction operand.
 * introduce a `zir.Decl` type for ZIR Module decls which holds
   content_hash and name - fields that are not needed for `zir.Inst`
   which are created as part of semantic analysis. This improves the
   function signatures of Module.zig and lowers memory usage.
 * the Str instruction is now defined to create an anonymous Decl and
   reference it.

7e58c56ca7 self-hosted: implement Decl lookup 
* Take advantage of coercing anonymous struct literals to struct types.
 * Reworks Module to favor Zig source as the primary use case.
   Breaks ZIR compilation, which will have to be restored in a future commit.
 * Decl uses src_index rather then src, pointing to an AST Decl node
   index, or ZIR Module Decl index, rather than a byte offset.
 * ZIR instructions have an `analyzed_inst` field instead of Module
   having a hash table.
 * Module.Fn loses the `fn_type` field since it is redundant with
   its `owner_decl` `TypedValue` type.
 * Implement Type and Value copying. A ZIR Const instruction's TypedValue
   is copied to the Decl arena during analysis, which allows freeing the
   ZIR text instructions post-analysis.
 * Don't flush the ELF file if there are compilation errors.
 * Function return types allow arbitrarily complex expressions.
 * AST->ZIR for function calls and return statements.

b4eac0414a stage2: hook up Zig AST to ZIR 
* Introduce the concept of anonymous Decls
 * Primitive Hello, World with inline asm works
 * There is still an unsolved problem of how to manage ZIR instructions
   memory when generating from AST. Currently it leaks.
