[LLVMdev] API CHANGE: set_gcc_path removed from libLTO C binding

[Nick Lewycky]

If you haven't written code to the libLTO interface, you can stop 
reading now.

As of r77960 I've removed the lto_codegen_set_gcc_path call from libLTO. 
This wasn't in the last LLVM release and has already been obsoleted by 
lto_codegen_set_assembler_path. This shouldn't be a problem for any 
libLTO users that I know of, but if you were using this, and you can't 
switch to set_assembler_path, please reply and explain your situation.
