fa7fd33a26 On x86, it's safe to treat i32 load anyext as a normal i32 load. Ditto for i8 anyext load to i16.

844731a7f1 Clean up the use of static and anonymous namespaces. This turned up
several things that were neither in an anonymous namespace nor static
but not intended to be global.

30562b7d44 Be more aggressive about tail-merging small blocks
if those blocks consist entirely of common instructions;
merging will not add an extra branch in this case.

51b2b9e29e Further rework of tail merge algorithm. Not quite
semantically identical, but little difference in
either results or execution speed; but it's much
easier to read, at least IMO.

e4fc1ccd4d One real change - don't hoist something that's trivially rematerializable. It's
possible for it to produce worse code than before.

The rest of this patch is code cleanup.

which is close enough and doesn't cause heap traffic.
