The parser previously parsed labels and could attach them to control flow
structures, but did not maintain the context necessary to correctly parse
branches. Support parsing labels as both names and indices in IRBuilder,
handling shadowing correctly, and use that support to implement parsing of br.

Add a `visitFunctionStart` function to IRBuilder and make it responsible for
setting the function's body when the context is closed. This will simplify
outlining, will be necessary to support branches to function scope properly, and
removes an extra block around function bodies in the new wat parser.

Parse loops in the new wat parser and add support for them to the IRBuilder.

Somewhat counterintuitively, the text syntax for a folded `if` allows any number
of folded instructions in the condition position, not just one. Update the
corresponding `foldedinsts` parsing function to parse arbitrary sequences of
folded instructions and add a test.

The new wat parser previously returned InstrT types when parsing individual
instructions and collected InstrsT types when parsing sequences of instructions.
However, instructions were always actually tracked in the internal state of the
parsing context, so these types never held any interesting or necessary data.
Simplify the parser by removing these types and leaning into the pattern that
the parser context will keep track of parsed instructions.
This allows for a much cleaner separation between the `instrs` and
`foldedinstrs` parser functions.

Parse both the straight-line and folded versions of if, including the
abbreviations that allow omitting the else clause. In the IRBuilder, generalize
the scope stack to be able to track scopes other than blocks and add methods for
visiting the beginnings of ifs and elses.

And put the new files in a new source directory, "parser". This is a rough split
and is not yet expected to dramatically improve compile times. The exact
organization of the new files is subject to change, but this splitting should be
enough to make further parser development more pleasant.
