8b14a499f9 Make the test a bit more strict.
Before it would pass even if @b or @c ended up pointing to a variable named
@a123.

f531e92671 Add a plugin testcase for merging weak variables.
I initially thought I could implement COMDATs with aliases by just
internalizing GVs instead of dropping them. This is a counter
example: Internalizing one of the @a would make @b and @c point
to different variables.
