Convert run-test bash build scripts to python.
Tests use the build script for two distinct purposes:
* Some tests generate their source code before completion.
Keep this code in bash for now and rename it "generate-sources".
* To customize arguments passed to the default compilation script.
Since the default compilation script is in python, make this
a normal python call, and add any customization as arguments.
This speeds up the run-test compilation. There was small cost to
pay due to the switching from python to bash to python.
This added up for the thousands of run-test compilations that we do.
It also removes the need for argument parser in the default script.
We could also remove the data passing via environment (to-do later).
It moves the definition to more build-system-like look and feel.
Test: The outputs are bit-for-bit identical as before.
