Since branches to loops go to the beginnings of the loops, they should values matching the input types for the loops (which are always none because we don't support loop input types). IRBuilder was previously using the output types of loops to determine what values the branches should carry, which was incorrect. Fix it.
The new wat parser is much more strict than the legacy wat parser; the latter accepts all sorts of things that the spec does not allow. To ease an eventual transition to using the new wat parser by default, update the tests to use the standard text format in many places where they previously did not. We do not yet have a way to prevent new errors from being introduced into the test suite, but at least there will now be many fewer errors when it comes time to make the switch.

There was a problem hiding this comment.
The original NaNs here have invalid payloads. The spec for this is here.
The fNMag production 'nan:0x' n:hexnum => nan(n) has a side condition (1 <= n < 2^signif(N)) and signif(32) = 23, so the largest allowed NaN payload for a 32-bit float is 2^23 - 1 = 0x7FFFFF.
