[ORC] Drop Comdat when discarding IR symbol
According to the IR verifier, "Declaration[s] may not be in a Comdat!"
This is a re-commit of 76b3f0b4d5a0b8c54147c4c73a30892bbca76467 with
updates to the test:
* Force emission of the extra-module, to trigger the bug after D138264,
by providing a second symbol @g, and making the comdat nodeduplicate.
(Technically only one is needed, but two should be safer.)
* Name the comdat $f to avoid failure on Windows:
LLVM ERROR: Associative COMDAT symbol 'c' does not exist.
