stage2/wasm: write exports on flush, cleanup
...
Exports now have a dirty flag and are rewritten on flush if this flag
has been set.
A couple other minor changes have been made based on Andrew's review.

stage2/wasm: implement basic container generation
...
Thus far, we only generate the type, function, export, and code
sections. These are sufficient to generate and export simple functions.
Codegen is currently hardcoded to `i32.const 42`, the main goal of this
commit is to create infrastructure for the container format which will
work with incremental compilation.

This is part of an ongoing effort to reduce size of in-memory AST. This

compiler.
This is a API breaking change for consumers of the self-hosted parser.

stage2: implement while loops (bool condition)
...
* introduce a dump() function on Module.Fn which helpfully prints to
stderr the ZIR representation of a function (can be called before
attempting to codegen it). This is a debugging tool.
* implement x86 codegen for loops
* liveness: fix analysis of conditional branches. The logic was buggy
in a couple ways:
- it never actually saved the results into the IR instruction (fixed now)
- it incorrectly labeled operands as dying when their true death was
after the conditional branch ended (fixed now)
* zir rendering is enhanced to show liveness analysis results. this
helps when debugging liveness analysis.
* fix bug in zir rendering not numbering instructions correctly
