[LLVMdev] -debug in make check

[reed kotler]

I'd like to have some .ll tests in make check where I verify that 
certain DAG nodes are being processed. Normally I would compile with 
-debug and look for them.

Is it possible to scan the stdout instead of the .s file from a .ll in 
make check?

Probably I would want to process the file twice, once to verify that the 
nodes occur in the dag and then to look for some patterns in the .s file.
