Konstantin Belousov 39d70f6b80 Provide deterministic (and somewhat useful) value for RDPID result,
and for %ecx after RDTSCP.

Initialize TSC_AUX MSR with CPUID.  It allows for userspace to cheaply
identify CPU it was executed on some time ago, which is sometimes useful.

Note: The values returned might be changed in future.
