[mono] Fix LLVMArgWasmVtypeAsScalar when a method doesn't set its r…
Browse files Browse the repository at this point in the history 
…eturn value (#101299)

* Update mini-llvm.c

I think we should handle it here, the same way as `LLVMArgVtypeAsScalar`. They differ only in the return type, where the wasm specific one is returning type of the element instead of `int`.

* Include TrimmerRootDescriptor only on Apple mobile platforms

* Update src/mono/mono/mini/mini-llvm.c
