[Issue 16043] Wrong line number for closure in -vgc

The shown line number is not wrong.

The closure environment that is closing variable foo, is allocated at the start
of function test() == line 1. The delegate literal at line 4 just refers it.

So, the issue would be:
1. the message text that is not enough helpful (diagnostic), or
2. lack of information about the location where the closed variable 'foo' is
used from (enhancement).
