Inspired by some fixes in PMIx: * @Matthew-Witlock's fix in openpmix/openpmix@47b6634 (openpmix/openpmix#3670) * @Matthew-Witlock's fix in openpmix/openpmix@08c22de (openpmix/openpmix#3709) * @Matthew-Witlock's fix in openpmix/openpmix@36df200 (openpmix/openpmix#3732) Fix some logic errors in opal_bitmap.c:opal_num_set_bits(): the parameter is supposed to be the number of bits, not number of elements. The fixes here are essentially the same as Matthew's, but with some stylistic changes. It doesn't look like this function is invoked anywhere in the code base, which is why we hadn't previously noticed these issues. That being said, if we have the code, it should be correct. This commit therefore also adds some tests for the opal_bitmap_num_set_bits() function to "make check" to make sure that it's actually working properly. Signed-off-by: Jeff Squyres <jeff@squyres.com>

If the length being counted in
pmix_bitmap_num_set_bitsis too many bits into the final value, the bit shift becomes 0 since the literal1is an int.1LLis at least 64 bits long, solving the issue.
