Avoid debugging and assertions in wheels

Describe the bug
Performance analysis indicates that the binary wheels probably are not build with debugging and assertions disables.
This gives a significant performance hit.

Software versions

• OS and version: [e.g. Ubuntu 18.04]
• Python version: [e.g. 3.7]
• MonetDBe-Python version: [e.g. 0.7]

would adding -DCMAKE_BUILD_TYPE=Release be enough?

[arjenderijke]

That should be the solution, but it is not completely implemented in the CMake code of MonetDB. I will add that to my todo list.

[arjenderijke]

BTW @mlkersten i would like to have the scripts you use for your performance analysis, to verify the implemented solution.

[njnes]

for now use
-DCMAKE_BUILD_TYPE=Release
-DASSERT=OFF

Last is enabled because we build 'a' non released hg/git checkout. If you build from a clean tar (ie no .hg/.git directory) the -DASSERT should not be needed.

0.8.3 with build type release has been published and uploaded to pypi.
