676dee6ae9 Put int the getReg cast optimization from x86 so that we generate fewer 
move instructions for the register allocator to coalesce.

9f54791d54 Recommend that new users read the documentation before they get started, 
with a little twist of humor. This more than anything else will help
people get started with LLVM.

single call site.

7a7cb4c99b Added rough support for dejagnu testing. Changes need to be made to autoconf to provide the target_triplet and to check for 'grep -C' which would be used instead of the python script we have now. Eventually the python script should be converted to bash. 
The dejagnu-clean needs to be fixed to use find.
