x86: Move miscreg initialization to the ISA class.

The initCPU function was setting a lot of values to zero or other
initial values, but that's something the ISA object can do as part of
its clear() method. This gets rid of a lot of code that was
individually zeroing registers, and also centralizes responsibility
for those registers in the ISA.
