configs: Use the same address ranges for dir and mem_ctrls
In Ruby, for every directory we create one memory controller for every
range in the memory ranges. Previously the memory controllers and the
directories created their address ranges independently and as a result
a mismatch was possible. In fact, we assinged an interleaved address
range with hasing for the memory controllers while the corresponding
directories would be assigned the same interleaved address range
without hashing.
This change uses the address range of the memory controllers to
populate the list of address ranges for the corresponding directory
and avoid bugs due to code duplication.

misc: Appease GCC 8
GCC 8 adds a number of new warnings to -Wall which generate errors.
- Fix memset to 0 for structs by adding casts.
- Fix cast with const when the const was ignored.
- Fix catch a polymorphic type by value
We now compile with GCC 8!

than updating pybind to the HEAD, we'll wait for a new release. The last

The code will not compile if the preprocessor defines are removed. The

persistent_randomize array are undefined. It's not clear what they should
be from the current code.
5ab13e2deb shows when the lines were last modified. The functionality

is enabled by removing defines. The code rots and sits in the source
