Tomasz Miąsko 8c8225afe8 Remove mono item collection strategy override from -Zprint-mono-items
Previously `-Zprint-mono-items` would override the mono item collection
strategy. When debugging one doesn't want to change the behaviour, so
this was counter productive. Additionally, the produced behaviour was
artificial and might never arise without using the option in the first
place (`-Zprint-mono-items=eager` without `-Clink-dead-code`).  Finally,
the option was incorrectly marked as `UNTRACKED`.

Resolve those issues, by turning `-Zprint-mono-items` into a boolean
flag that prints results of mono item collection without changing the
behaviour of mono item collection.

For codegen-units test incorporate `-Zprint-mono-items` flag directly
into compiletest tool.

Test changes are mechanical. `-Zprint-mono-items=lazy` was removed
without additional changes, and `-Zprint-mono-items=eager` was turned
into `-Clink-dead-code`.  Linking dead code disables internalization, so
tests have been updated accordingly.
