Add simple key ranges where the address range lies within a single base segment for a single space.
NOTE: start and end addresses must have the same address space!
@param keyRangeList the list to store key ranges into
@param start the start address
@param end the end address
@param absolute true if the address are to be encoded as absolute (not relative to the
 image base
@param create if true, this method will add new address bases that are required to
store addresses in that database that have that address base
