ValueFlow: Small cleanups
TemplateSimplifier: Fixed crash caused by null pointer dereference. I don't have a testcase. But the code is suspicious, in the loop we check if tok3 is null and then in the loop head we call tok3->next().
Fixed #5981 (FP: nullPointer on repeated switch)
Fixed copy and paste error (Coverity-ID: 1226262 Copy-paste error).
Tokenizer: Added missing comma in string array initialization (This fixes Coverity-ID: 1226263 Missing comma in a string array initialization).
Add simple xml debug output. When both --xml and --debug is used there will be xml debug output.
Get rid of tokAt() and strAt() in trivial cases.
