This patch kit:
* adds minimal Python bindings for libgdiagnostics.so (below contrib)
* implements a new dg-lint tool (below contrib) to detect for
common mistakes in our testsuite, using Python 3 (and the above
bindings)
* fixes a bunch of issues reported by the tool
I've only tested the testsuite fixes on x86_64-pc-linux-gnu; there
were some new PASSes and no regressions, but I haven't tested the
tests on non-x86 archs.
Thoughts?
