This patchset introduces the idef-parser for target/hexagon. It's the ninth iteration of the patchset and includes fixes suggested in previous iterations.
`idef-parser` is a build-time tool built using flex and bison. Its aim is to generate a large part of the tiny code generator frontend for Hexagon. The prototype of idef-parser has been presented at KVM Forum 2019 ("QEMU-Hexagon: Automatic Translation of the ISA Manual Pseudocode to Tiny Code Instructions"): https://www.youtube.com/watch?v=3EpnTYBOXCI `target/hexagon/idef-parser/README.rst` provides an overview of the parser and its inner working. A couple of notes: * These commits build successfully on the CI (including using clang), with one notable exception. Presently, the `build-user-hexagon` job fails due to not being able to find `flex`/`bison`. This is due to the `debian-hexagon-cross` container not being built by the CI. As such the `debian-hexagon-cross` container will have to be manually rebuilt before merging. * `checkpatch.pl` complains about the `_Generic` macro `OUT_IMPL` in `idef-parser/parser-helpers.h` which we believe to be correctly formatted. The complaints concern the `:` in the type "labels" of the macro, and also the `default:` label. * The eight patch, which introduces `flex`/`bison` as new build pre- requisites using `libvirt-ci`, will update `tests/lcitool/libvirt-ci` to a new upstream commit which includes these package mappings.
