Code in conditional compilation branches is not exported

[abdulowork]

Reproduction

This is likely a known issue, but I didn't find mentions in the issues yet. Basically, from the following code:

#if FOO
public func first() {}
#else
public func second() {}
#endif

public func third() {}

only the third function is exported by jextract as of 5764bc2a1b706056121109dc0ab14fd3d771cbc5

Appreciate all the issues, will make it easier to tick them off one by one. Thanks!

I wonder what we should do though, export both but what if calling rhe unavailable one, I guess runtime thrown an exception from the thunk hm
