[PATCH] i386 sparsemem for single node systems

Allow SPARSEMEM to be enabled on non-numa x86 systems.  This is made
dependant on EXPERIMENTAL also being set.  When an in-tree user (such as
simulated numa) exists it should be made dependant on that.

The plan is to have no options and no selector as normal when
!EXPERIMENTAL.  When EXPERIMENTAL we enable the FLATMEM and SPARSEMEM
options for X86_PC whilst maintaining DISCONTIGMEM and SPARSEMEM for NUMA.
