[Tarantool-patches] [PATCH v2 luajit 0/5] Handle all errors during stitching

[Sergey Kaplun]

This patchset handles all possible error types that may be observed
during stitching. The first 2 patches add an option to enable table bump
optimization for CMake options and add it to the CI exotic build
correspondingly. The third patch enhances the <jit/parse.lua> testing
utility to return IRs of aborted trace as well. Also, the reason for the
abort of a trace may be examined. The last 2 patches handle all possible
errors during stitching and ensure that the output of `jit.dump()` is
valid for all cases.
