Markus Lehtonen e866b6ee1c Implement RDT detection in go
Get rid of the dependency on intel-cmt-cat library and rdt helper
binaries written in C. Significantly simplifies the build procedure.

Implements minimal support (in assembler) for getting the raw data from
the CPUID instruction. Also, implement a stub so that the code works on
other architectures than amd64, too.
