dimgigov 0b887b92d3 selfhost: for-in support for Channel<T>; fix break/continue C codegen
- lib/Channel.bux: add Channel_Recv_Ok<T> for use in for-in desugaring
- hir_lower.bux: Channel for-in desugars to while+recv_ok pattern
- c_backend.bux: emit 'break;' / 'continue;' with semicolon, fix missing
  semicolon when break/continue inside if-block
- bootstrap/hir_lower.nim: skip generic methods in vtable generation to
  avoid referencing non-existent monomorphized C functions
