Summary:
This patch implements a unified way of cleaning the build folder of each
test. This is done by completely removing the build folder before each
test, in the respective setUp() method. Previously, we were using a
combination of several methods, each with it's own drawbacks:
- nuking the entire build tree before running dotest: the issue here is
that this did not take place if you ran dotest manually
- running "make clean" before the main "make" target: this relied on the
clean command being correctly implemented. This was usually true, but
not always.
- for files which were not produced by make, each python file was
responsible for ensuring their deleting, using a variety of methods.
With this approach, the previous methods become redundant. I remove the
first two, since they are centralized. For the other various bits of
clean-up code in python files, I indend to delete it when I come
across it.

I have found LLDB cannot find separate debug info of Fedora /usr/bin/gdb.
It is because:
lrwxrwxrwx 1 root root 14 Jan 25 20:41 /usr/bin/gdb -> ../libexec/gdb*
-rwxr-xr-x 1 root root 10180296 Jan 25 20:41 /usr/libexec/gdb*
ls: cannot access '/usr/lib/debug/usr/bin/gdb-8.0.1-35.fc27.x86_64.debug': No such file or directory
-r--r--r-- 1 root root 29200464 Jan 25 20:41 /usr/lib/debug/usr/libexec/gdb-8.0.1-35.fc27.x86_64.debug
FYI that -8.0.1-35.fc27.x86_64.debug may look confusing, it was always just
.debug before.
Why is /usr/bin/gdb a symlink is offtopic for this bugreport, Fedora has it so
for some reasons.
It is always safest to look at the .debug file only after resolving all
symlinks on the binary file.
