As suggested by Avi, introduce accessors to read/write guest registers.
This simplifies the -cache_regs/-decache_regs interface, and improves
register caching which is important for VMX, where the cost of
vmcs_read/vmcs_write is significant.

Accurate regs_dirty information is useful for converting the emulator,
so that you can do something like:
emul_register_write(ctxt, reg, val)
