[PATCH][x86] Support clflushopt, xsaves, xsavec.


Hi,

This patch add support for xsavec, xsaves ISA extensions, introduced in
[1], and clflushopt introduced in [2].

[1]http://www.intel.com/content/www/us/en/processors/architectures-software-developer-manuals.html
[2]http://software.intel.com/en-us/file/319433-018pdf

Bootstraps, passes make-check.
Ok for trunk?
