49488fa0a0 Ruby: Fix bad join in ActionControllerHelperMethod
```
[2022-01-25 12:35:14] (234s) Tuple counts for ActionController::ActionControllerHelperMethod#class#ff/2@ef816fil after 1.5s:
                      7685     ~0%     {3} r1 = JOIN ActionController::ActionControllerContextCall#ff#shared WITH Method::Method::getName_dispred#ff ON FIRST 1 OUTPUT Rhs.1, Lhs.1 'controllerClass', Lhs.0 'this'
                      13198    ~0%     {3} r2 = JOIN r1 WITH Constant::ConstantValue::getStringOrSymbol_dispred#ff_10#join_rhs ON FIRST 1 OUTPUT Lhs.1 'controllerClass', Lhs.2 'this', Rhs.1
                      15835365 ~4%     {5} r3 = JOIN r2 WITH AST::AstNode::getEnclosingModule_dispred#ff_10#join_rhs ON FIRST 1 OUTPUT Rhs.1, "helper_method", Lhs.0 'controllerClass', Lhs.1 'this', Lhs.2
                      12943    ~1%     {4} r4 = JOIN r3 WITH Call::MethodCall::getMethodName_dispred#ff ON FIRST 2 OUTPUT Lhs.4, Lhs.2 'controllerClass', Lhs.3 'this', Lhs.0
                      1146184  ~0%     {4} r5 = JOIN r4 WITH Expr::Expr::getConstantValue_dispred#ff_10#join_rhs ON FIRST 1 OUTPUT Lhs.3, Rhs.1, Lhs.1 'controllerClass', Lhs.2 'this'
                      212      ~0%     {2} r6 = JOIN r5 WITH project#Call::Call::getArgument_dispred#fff ON FIRST 2 OUTPUT Lhs.3 'this', Lhs.2 'controllerClass'
                                       return r6
```

Joining on enclosing module and name simultaneously yields a much better join.

67962cb93d Ruby: Fix bad join in access predicate
Joining on variable name alone is a bad thing:

```
[2022-01-25 11:13:20] (228s) Tuple counts for Variable::Cached::access#ff#shared/3@868b54tu after 3m37s:
                      112554    ~0%     {3} r1 = JOIN Variable::VariableReal::getNameImpl_dispred#ff WITH Variable::VariableReal::getDeclaringScopeImpl_dispred#ff ON FIRST 1 OUTPUT Lhs.1, Lhs.0 'arg2', Rhs.1 'arg1'
                      561015756 ~1%     {3} r2 = JOIN r1 WITH Variable::variableName#ff_10#join_rhs ON FIRST 1 OUTPUT Rhs.1 'arg0', Lhs.2 'arg1', Lhs.1 'arg2'
                                        return r2
```

This change ensures that we join on name and scope simultaneously.

Harry Maclean
4f7f92490a Distinguish regex components from strings
Create a set of classes for components of regex literals,
separate from those of string literals. This allows us to special-case
components of free-spacing regexes (ones with the /x flag) to not have a
`getValueText()`.

This in turn is useful because our regex parser can't handle free-spacing
regexes, so excluding them ensures that we don't generate erroneous
ReDoS alerts.
