Refactor the same expression check
...
Work out if a function is inconclusive when creating the entry in the
Expressions class instead of when checking the counts at the end. Store
the result in a new bool flag in the ExpressionTokens helper struct.
The pointer to symbol database and ref to list of const functions are
temporarily stored in the Expressions helper class to avoid passing
them in too on every endExpr(tok) call.
Use a const reference to ExpressionTokens in the check loop to avoid
repeating the it->second several times, which clarifies what that code
does.

Whitespace was removed from the append data for every configuration
and every file: n(configuration) * n(files).
Removing whitespace immediately after the append data was read can
significantly reduce the execution time and memory usage.
It also allows further improvement because copies to the temporary
object appendCode are no longer needed.

Remove check for "this" inside Token class
...
The check hides real memory problems and is
also useless in most cases.

Also contains test order improvements from Johan Samuelson (#3116 ).
Run time went down from 15.15s to 14.95s for the case below.
Benchmarked using these settings:
- CXXFLAGS="-O2 -g -NDEBUG"
- time -p cppcheck.git -q --std=posix --enable=all --inconclusive -Dfoo .

Fix for same expression separated by commas
...
The code branch tested by the previous check for && is now different, so
I've changed the test to use == instead. There was also a missing case
when the expression was followed by a comma instead of being preceded by
one.

Improved same expression check for ticket #3274
...
Expand the logic for the check for the same expression on both sides of
the || and && operators. Now expressions can be more complex, with the
"alt" variable helping to fudge operator precedence to avoid false
positives.
