Nathan Williams 8710820156 core: ensure that GMatchInfo and GRegex objects are freed properly 
In particular, g_regex_match() and g_regex_match_full() allocate a
match_info structure on both success and failure, so calling
g_match_info_free() only in the success case is insufficient.

BUG=None
TEST=Inspection
