Josh Stone 7a3108ff0f [CodeView] Allow empty types in member functions ...

Summary:
`CodeViewDebug::lowerTypeMemberFunction` used to default to a `Void`
return type if the function's type array was empty. After D54667, it
started blindly indexing the 0th item for the return type, which fails
in `getOperand` for empty arrays if assertions are enabled.

This patch restores the `Void` return type for empty type arrays, and
adds a test generated by Rust in line-only debuginfo mode.
