Manos Koukoutos c0956fbd1d [wasm] Fix bugs in inlining on 32-bit platforms
- Use the lowered 32-bit signature when linking the inlined and caller
  graphs.
- Tolerate non-projection uses of Call nodes when linking the graphs.
  These can be left over by Int64Lowering.
- Drive-by: Inline really small functions even if their call count is
  low.
