[Openmp-dev] Removing liboffload from repository

Hi all,

I'd like to propose removing liboffload (the 'offload/' directory) from 
the openmp repository.
1) This is an old dump from openmprtl.org which was never updated (The 
current version doesn't even build / work with newer software stacks!), 
even though Intel continued doing newer releases.
2) The library was never integrated into LLVM's build system, you have 
to manually call 'make' with the right parameters.
3) The library is meant for Intel's Xeon Phi Knights Corner coprocessor. 
AFAIK there only were variants of Knights Landing that serve as host 
processor (coprocessor cards were announced but never released). As of 
last year, even its successor Knights Hill has been declared dead and 
the whole line is now discontinued.

With libomptarget getting more mature it's quite confusing for our users 
that there are two libraries apparently doing offloading.
