Artem Dergachev 99b94f29ac [analyzer] LoopUnrolling: fix crash when a parameter is a loop counter. ...

When loop counter is a function parameter "isPossiblyEscaped" will not find
the variable declaration which lead to hitting "llvm_unreachable".
Parameters of reference type should be escaped like global variables;
otherwise treat them as unescaped.
