The extended trace register list is needed in multiple locations; the CPU
class is the logical module to contain this information.
Increased number of x86 registers to be traced; we can remove those
that prove unusable for fault-space pruning later on.

This allows a register to be a member of multiple UniformRegisterSets.
Needed to architecture-specifically store, e.g., a list of registers to
record in traces.
