Subject: [PATCH lib/bitmap 7/9] lib: test_bitmap: add tests for "N" alias

From: Paul Gortmaker <paul.gortmaker@...driver.com>

These are copies of existing tests, with just 31 --> N.  This ensures
the recently added "N" alias transparently works in any normally
numeric fields of a region specification.
