Some of the example and gtest tests parse wat. Update them to use the new wat parser, fixing problems with their text input. In one case, comment out an outlining test entirely for now because the new parser produces different IR that changes the test output, but it is not obvious how to understand and fix the test.

Why is there such a big diff here?

The extra two blocks mean that the top-level walker loop has two more control flow structures to pop off the control structure queue, generating more logs. The new parser also inserts a couple pops that are missing in the input that the old parser did not generate.

Which two new blocks? Sorry, I'm missing something here.

Ah, those would be the blocks the new parser generates for the catch clauses in the input. The input does not include the implicit pop instruction at the beginning of the catch clauses, so the old parser just used (drop ...) as their bodies. Since the new parser inserts the pop instruction, the catch clauses have multiple top-level instructions, so they are wrapped in a block.
(And if something seems fishy about this, it may help to know that the input program would not pass validation)
