New Revision: 157030

URL: http://llvm.org/viewvc/llvm-project?rev=157030&view=rev
Log:
Remove a test that was only testing for physreg joining.

This is the same as the other tests: Clever tricks are required to make
the arguments and return value line up in a single-instruction function.
It rarely happens in real life.

We have plenty other examples of this behavior.
