Adds new visitBreakWithType and visitSwitchWithType functions to the IRBuilder API. These functions work around an assumption in IRBuilder that the module is being traversed in the fully nested format, i.e., that the destination scope of a break or switch has been visited before visiting the break or switch. Instead, the type of the destination scope is passed to IRBuilder.

Changes the controlFlowQueue used in stringify-walker to push values of Expression*, This ensures that we walk the Wasm module in the same order, regardless of whether the control flow expression is outlined.

Besides If, no control flow structure consumes values from the stack. Fix a
bug in IRBuilder that was causing it to pop control flow children. Also fix a
follow on bug in outlining where it did not make the If condition available on
the stack when starting to visit an If. This required making push() part of
the public API of IRBuilder.
As a drive-by, also add helpful debug logging to IRBuilder.

Checking a couple of testing TODOs off and adding more tests of the outlining pass for outlining:
- a sequence at the beginning of an existing function
- a sequence that is outlined into a function that takes no arguments
- multiple sequences from the same source function into different outlined functions
|

Adds an outlining pass that performs outlining on a module end to end, and two tests.
