Only return the function token from checkTokenInsideExpression when it
might be one the argument (hence keeping a pointer to one of them).
Otherwise, we can directly skip to the token after the function call.

Improve isSameExpression for literals ( #2514 )
...
Improve isSameExpression() for literals with same value but different
representation, for example the following different ways of
representing 9 as double: 9.0, 0.9e1 and 0x1.2p3.
With this change, cppcheck can (for example) correctly detect that the
else if statements are always false in the following example:
void f(double x) {
if (x < 9.0) {}
else if (x < 0x1.2p3) {}
else if (x < 0.9e1) {}
}

Fix 9577 (endless recursion in Valueflow::bifurcate()) ( #2492 )
...
Ensure bifurcate() does not recurse endlessly where a variable is
initialized recursively, or a variable is initialized as x(0) or x{0}
followed by a recursive assignment (for example int x(0); x = x / 1;).
The first case is solved by bailing out if there initialization is done
using x(0) or x{0}, the second by adding a missing depth argument to a
recursive call.

Fix 9546: properly check that the bound is the size ( #2475 )
...
Previously, as the check was done on the token and not on the ast,
`i <= v.size()` and `i <= v.size() - 2` would both raise the same
warning.
This patch fixes this, but this mean the check is only done when the
condition if `i <= v.size()`. Any other (more complex) condition is
ignore, and so we have false negative for instance with
`i <= v.size() + 1`.

This workarounds false positives 'Parameter can be declared with const [constParameter]'
when said parameter is used in constructor call. It assume the
constructor call might change the parameter (without any checks.
The drawback is that we have false negative, in cases where we could
check the constructor actually takes a const reference, or a copied by
value parameter.

errorlogger.cpp: Handle empty file-name like "*" (unmatchedSuppression) ( #2440 )
...
Using "--suppress=unmatchedSuppression" did not suppress the error-id in
all files, one needed to specify "*" as file-name. This commit also
allows empty file-names to suppress "unmatchedSuppression", not only "*"
or the exact file-name.
The manual uses the following example for suppressions specified in a
file:
// suppress all uninitvar errors in all files
uninitvar
This example suggests that no "*" has to be used to get suppression in
all files. I think that the command line parameter should work in the
same way.

* Avoid some additional memleakOnRealloc false positives
checkReallocUsage() already contains code to suppress the
`p = realloc(p, size)` error message when the pointer has been
previously copied from another variable (hence there is an additional
copy of the original pointer value) within the same function, as in
the added realloc21() test case.
Extend this so that `p = *pp` and `p = ptr->foo` are also recognized
as copies from another variable with the same original pointer value,
as in the added realloc22() and realloc23() test cases.
