global: use pycompat.xrange()
On Python 3, our module importer automatically rewrites xrange()
to pycompat.xrange().
We want to move away from the custom importer on Python 3.
This commit converts all instances of xrange() to use
pycompat.xrange().

# dirstatenonnormalcheck.py - extension to check the consistency of the
# dirstate's non-normal map
#
# For most operations on dirstate, this extensions checks that the nonnormalset
# contains the right entries.
# It compares the nonnormal file to a nonnormalset built from the map of all
# the files in the dirstate to check that they contain the same files.
