[PATCH] [dwarfdump] Prettyprint DW_AT_APPLE_property_attribute bitfield values.

[David Blaikie]

Looks good to me - please submit.

(it seems most of our existing formatting doesn't put extra spaces - though we're not entirely consistent (strp has a leading space, exprloc (& maybe other FORM_data) has a trailing space (probably just because someone didn't handle the end case), etc)
