This aims to add support for __cpu_model and address Bug 25510. It uses
the code from lib/Support/Host.cpp for cpu detection, and creates
__cpu_model with that info.
Tested on OSX and built on Linux as well (though libgcc is the default).
The use of "asm" required -std=gnu99, hence the cmake change. Corrections
on better addressing this are welcome.
Previously reverted, up for review again to iron out outstanding issues.
