Reijo Tomperi 89fd5bacf9 Fix #2849, False positive: memory leak (using question mark operator)
http://sourceforge.net/apps/trac/cppcheck/ticket/2849
Simplify: *d = b ? b : a; into if-else
Simplify { ; { ; } } into { ; }
Removed one memleak test which should be redundant now as question marks
should not get into memleak check.
