SystemError raised by Python bindings on Python 3.5

[damienayers]

I seem to have encountered the issue described in ​swig/swig#567 in python 3.5

from osgeo import ogr

def make_geom():
    geom = ogr.Geometry(ogr.wkbPoint)
    geom.AddPoint_2D(0, 0)
    return geom

def gen_list(N):
    for i in range(N):
        geom = make_geom()
        yield i

N = 10
print('gen', list(gen_list(N)))

produces SystemError: <built-in function delete_Geometry> returned a result with an error set

The issue has been resolved in SWIG 3.0.8 but the bindings in the GDAL sources are generated with SWIG 2.0.12.

Regenerating the bindings with the latest SWIG resolves the issue, but also adds libpcre as a run-time dependency.

In 36845:

Regenerate Python bindings with SWIG 3.0.8 to avoid issue with Python 3.5. Add backward compatibility in Band.ComputeStatistics() to accept 0/1 as input instead of the expected bool value (fixes #6749)

In 36846:

Add new test step to test issue with Python 3.5 and older SWIG (refs #6749)
