CPU feature checking - require SSE4.2

The packages in the isa-support family probe for microprocessor Instruction Set Architecture features such as SSE3. By refusing to install on machines lacking a required feature, they allow ISA requirements to be handled in terms of package dependencies.

This is a mostly dummy package which checks for SSE4.2 and refuses to install on unsupported hardware.

SSE4.2 added string and text processing instructions that perform character searches and comparison on two operands of 16 bytes at a time. It is available on Intel processors since Nehalem (circa 2008), but notably not on anything AMD until the Bulldozer (15h, in 2011) and Jaguar (16h, in 2013) families.
