x86: allow pv guests to disable TSC for applications
Linux, under CONFIG_SECCOMP, has been capable of hiding the TSC from
processes for quite a while. This patch enables this to actually work
for pv kernels, by allowing them to control CR4.TSD (and, as a simple
thing to do at the same time, CR4.DE).
Applies cleanly only on top of the previously submitted debug register
handling patch.

Also clean up CR4 and EFER handling, and hack-n-slash header file
inclusion madness to get the tree building again.
