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.

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.
