As discussed in #2775 (comment) , this pr enables gdb back on the toolchain build scripts. It also updates the README to use the current toolchain name for the gdb section.
Add the HPDcache as another alternative for the cache subsystem.
The HPDcache is a highly configurable L1 Dcache that mainly targets high-performance systems.
The ID in the request from the load/store unit must be mirrored by the
Dcache in the response. This allows to match a given response to its
corresponding request. Responses can be given (by the Dcache) in a
different order that the one of requests.
This modification introduces a pending load table that tracks
outstanding load operations to the Dcache. The depth of this table is
a parameter in the target configuration package.

* Clean-up README.md and top-level directory
This removes the duplicate `scripts` and `util` directories. Furthermore
the README is condensed by collapsing the citation and adding the
CITATION file to the repository.

* Re-name icache req/rsp structs
The structs used to communicate with the icache have contained the
direction, which makes no sense for structs since they inherently don't
have any direction.
