[analyzer] Rename SymbolRef to SymExprRef

Hi, folk.

I found a declaration of SymbolRef confusing and embarrassing to percept the code easily, especially working along with SymbolVal and SVal. Every time it takes time to recall the correct aliasing in mind.

Now:

using SymbolRef = const SymExpr *;

Propose to:

using SymExprRef = const SymExpr *;

Please, share your thoughts.

I’m personally in favor of this. We have symbolic regions, values, expressions, so this rename would indeed have a benefit.

Alright. I`ll make a patch and then we can discuss it.
