Mark Johnston b34a6e0fed dtrace: Drop illumos ifdefs for CPU register definitions
These are fixed, so having upstream's version is not especially useful,
and the duplicated definitions make for confusing reading.  No
functional change intended.

* We make fsbase and gsbase part of the lwp context (since they're
* the only way to access the full 64-bit address range via the segment
* registers) and thus belong here too. However we treat them as
* read-only; if %fs or %gs are updated, the results of the descriptor
* table lookup that those updates implicitly cause will be reflected
* in the corresponding fsbase and/or gsbase values the next time the
* context can be inspected. However it is NOT possible to override
* the fsbase/gsbase settings via this interface.
*
* Direct modification of the base registers (thus overriding the
* descriptor table base address) can be achieved with _lwp_setprivate.
