53ff96ab08 [WebAssembly] Basic support for Wasm object file encoding.
With the "wasm32-unknown-unknown-wasm" triple, this allows writing out
simple wasm object files, and is another step in a larger series toward
migrating from ELF to general wasm object support. Note that this code
and the binary format itself is still experimental.

d29493db4e [WebAssembly] Add immediate fields to call_indirect and memory operators.
call_indirect, grow_memory, and current_memory now have immediate
operands in the 0xd binary encoding.

dc833052ac [WebAssembly] Fix for 0xc call_indirect changes
Summary:
Need to reorder the operands to have the callee as the last argument.
Adds a pseudo-instruction, and a pass to lower it into a real
call_indirect.

This is the first of two options for how to fix the problem.
