Similar optimization to the one for x64 at https://crrev.com/c/3154347. There is a change to VisitLoad, which should call GetEffectiveAddressMemoryOperand on the value node. This allows us to match the input operands to the value (S128Load64Zero node), while emitting instructions for the node (F64x2PromoteLowF32x4 node).

The CL provides a way for the embedder to hook in a special malloc-like allocator that will be used for zone allocations. An alternative approach would be to use weak functions with branches, checking whether the functions were available at link-time. Those branches could be optimized away with LTOs, so they would essentially be free. However, the weak function approach is not portable (e.g. there is no easy way to emulate it with msvc). The approach can be revisited if indirect call turns out to be expensive (e.g. on hardware with weak branch target predictors). The CL is a prerequisite for running PCScan in the renderer process.

i32 comparisons often compare against constants, in order to implement conditional branches. This CL optimizes such code by not loading the constant into a register first, but directly emitting the comparison. The code is shared for implementing {if} and {br_if} (and thereby makes those two methods more readable).
