Wasm tails calls expect particular alignment of call arguments: parameters area, which is padded to WasmStackAlignment, shall not contain any other fields (e.g. ExitFooterFrame). 

The expectation is the same for GenerateDirectCallFromJit, but I could not came up with failing test case. The initial frame is aligned by 16, fake frame size (56 @x64 or 44 @x86) and footer is (8 or 4).
