Dan Gohman bb3722430f [WebAssembly] Implement unaligned loads and stores.

Dan Gohman 87b4aa8914 [WebAssembly] Add an assert to sanity-check dead flags.
The WebAssemblyStoreResults pass runs before LiveVariables, so it doesn't
expect to have to keep dead flags up to date; check this with an assert.

Derek Schuff 9d77952332 [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.

Dan Gohman 391a98afd5 [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.
