dac1c75c50 [MergeFunc] Allow merging identical vararg functions using aliases 
Thanks to Nikita Popov for pointing out this missed case.

This is a follow-up to r351411, which disabled function merging for
vararg functions outright due to a miscompile (see llvm.org/PR40345).

f667646768 [MergeFunc] Prevent silent miscompile of vararg functions 
The function merging pass miscompiles identical vararg functions. The
forwarding thunk it emits doesn't forward the full variable-length list
of arguments. Disable merging for vararg functions for now.

I've filed llvm.org/PR40345 to track the issue.
