d8e7e9176b Fix FN with known condition and sizeof 
cppcheck behaved differently if sizeof was to the left or right of the
comparison. In order to fix this, we cannot break the while loop until
all operands have been processed.

1e679cc5d1 Fix #9635 (FP: Memory leak with comma operator in if-statement) 
When checking for comparisons in if-statements, if there are comma
operators in the if-statement, skip until after the last comma.

Merge pull request #2703 from rikardfalkeborn/9652-fp-function-call-cast-config 
Fix #9652 (fp memleak with function call with cast)

4996ec190e Fix #9652 (fp memleak with function call with cast) 
When the first argument was (void *)(1), at the start of the second
iteration, arg was pointing to the "1", which caused problems for
nextArgument(), which saw the ")" as the next token and returned
nullptr, signalling that there are no more arguments.

Instead, save the first token in the argument, which makes
nextArgument() do the right thing.

d5345052ab Fix #9793 (false positive, memleak with lambda) 
Skip scopes with lambdas (similar to how checkleakautovar does). In
order to fix this when the lambda is inside a for loop, make
hasInlineOrLambdaFunction() recursive. This should be what all existing
users want.

5a3789a23f 9769: Improve value flow for ternary operator 
In some cases, the condition of the ternary operator is assigned a known
value after the two possible results, and in such cases, we would not
take the opportunity to assign a value to the ternary operator (and to
the other parents in the ast).
This patch adds this capability.
