Thomas Jarosch ec21134817 Fix false negatives for local suppressions
Introduce a new bool setting jointSuppressionReport
that will be set by the analyseWholeProgram() code path.

When the flag is enabled, unmatched suppressions are
collected after running the final whole program analysis
to prevent false positives for the unusedFunction check.

The check functions in the unit test
for single / multi file suppressions were unified.

Thomas Jarosch cd4c297dce Fix segfault in template simplifier
When something parsing the template syntax
went wrong, "tok2" was NULL and resulted
in deleting all remaining tokens. Whoops.

Triggered by gcc test suite:
gcc/testsuite/g++.dg/cpp0x/variadic87.C

Tracked down the source of the bug with
valgrind's "--track-origins=yes" switch.

Thomas Jarosch 58cb6cc116 Add new "style" check to catch redundant pointer operations
Doing "&*some_ptr_var" is redundant and might be the remainder
of a refactoring. Warnings for expanded macros are excluded though:
They are often used with and without pointers and
do something like this: "func(&(*macroarg))".

The new check is fully AST based and was given
strong false positive testing on a large code base.

Thomas Jarosch 10fffbfce0 Use unsigned int for all flags

Thomas Jarosch 1cc85bfce3 Add bounds check to getVariableFromVarId()
While poking around the memory leak check,
I managed to trigger an out-of-bounds access
in the symbol database.

Fix it by sanity checking the variable id
passed to getVariableFromVarId().

Token::Match( "sizeof %varid%" ) did match it -> FP.

This fix moves the code away from header file and ensures _instances remains valid during termination.
