[RFC PATCH 00/10] target/hexagon: introduce idef-parser

[Alessandro Di Federico]

From: Alessandro Di Federico <ale@rev.ng>

This patchset introduces the idef-parser for target/hexagon.
It is based on "[PATCH v8 00/35] Hexagon patch series".

`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 Pseudcode
to Tiny Code Instructions"):

`target/hexagon/idef-parser/README.rst` provides an overview of the
parser and its inner working.

Please consider this an RFC, this is our first large patchset. Feedback
is more than welcome.

A couple of notes:

* `idef-parser` also supports certain things that are not used in the
  most recently submitted version of the "Hexagon patch
  series". However, they will be needed and stripping them out of the
  parser is quite a bit of work.
* checkpatch.pl complains on a single macro which has a trailing
  semi-colon, which is required.

  target/hexagon: update MAINTAINERS for idef-parser
