This is more modern and (IMHO) easier to read than that old C typedef
syntax.

Applies the changes in #2065, and temprarily disables the hook since it's too slow to run on a change this large. We should re-enable it in a later commit.

Mass change to apply clang-format to everything. We are applying this in a PR by me so the (git) blame is all mine ;) but @aheejin did all the work to get clang-format set up and all the manual work to tidy up some things to make the output nicer in #2048

an if-else.
If an if sets a local,
(if
(..condition..)
(set_local $x (..value..))
)
we can turn it into
(set_local $x
(if
(..condition..)
(..value..)
(get_local $x)
)
)
This increases code size and adds a branch in the if, but allows
the set to be optimized into a tee or optimized out entirely. In
the worst case, other optimizations can break up an if with a copy
in one of its arms later.
Includes a determinism fix for EquivalentSets, which this patch
triggered.

If locals are known to contain the same value, we can
* Pick which local to use for a get_local of any of them. Makes sense to prefer the most common, to increase the chance of one dropping to zero uses.
* Remove copies between a local and one that we know contains the same value.
This is a consistent win, small though, around 0.1-0.2%.
