Fix potential use-after-free in WastLexer (#626)
Fixes issue #623.
* Move Token into its own file.
* Add WastParser tests. These ones are used because the source text is
very large, and it may be useful to generate parser tests
programmatically in the future too.
* Reorganize TokenType by the union data member it uses. This makes it
easier to determine which member needs to be
constructed/copied/destroyed.
- Bare (no data)
- Literal
- Opcode
- String
- Type
* Make Token store its string/literal data directly, rather than share
with lexer. This actually fixes the bug.
* Fix a couple of line-printing bugs:
- Very long tokens (e.g. "a" 20000 times) are now clamped to 80 chars.
- Very long lines are displayed properly in errors (e.g. a line with
65000 columns).
