[LLVMdev] [PATCH] enhance llvm-top

[Reid Spencer]

Hi Holger,

I applied this patch, with a few modifications. The reason the debug
option doesn't work is because of the LLVM makefile system. Its not
possible to do optimized and debug at the same time. In the future
(after the makefile improvements in the support module), this will be
possible.

Reid.
