3fcdebf45b [WebAssembly] Support constant offsets on loads and stores
This is just prototype for load/store for i32 types. I'll add them to
the rest of the types if we like this direction.

1a6c4af7ce [WebAssembly] Fix dominance check for PHIs in the StoreResult pass
When a block has no terminator instructions, getFirstTerminator() returns
end(), which can't be used in dominance checks. Check dominance for phi
operands separately.

Also, remove some bits from WebAssemblyRegStackify.cpp that were causing
trouble on the same testcase; they were left behind from an earlier
experiment.
