This patchset introduces the idef-parser for target/hexagon.
It's the fourth 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 Pseudcode
to Tiny Code Instructions"):

`target/hexagon/idef-parser/README.rst` provides an overview of the
parser and its inner working.
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.
* The build on the CI fails for the cross-i386-* jobs. This seems to be
due to the fact that, despite we specified glib as a native
dependency, meson still chooses the i386 bit version of the library,
as opposed to the x86-64.
Help on this matter is appreciated.
The `clang-user` build fails too, but seems to be due reasons not
concerning this patchset.
* Unlike the last iteration of this patchset, we no longer use local
temps, which were detrimental for performance. Now, in order to
handle side effects in ternary operators, the parser keeps track of
nested ternary operators and their conditions. We then exploit that
information to turn the side effect itself into a `movcond`. This is
done by emitting a series of `and` instructions on the nested
ternary operator conditions.
