It is my mistake in naming the function as getInitialExprFromCapturedExpr(). It should have been getCapturedExprFromImplicitCastExpr( ). The function extracts the OMPCapturedExpr from within the clause.  
clause->getCondition() does not give me the OMPCapturedExpr. 
```
(gdb) NoContextC->getCondition()->dump()
ImplicitCastExpr 0x678640 'int' <LValueToRValue>
  `-DeclRefExpr 0x678620 'int' lvalue OMPCapturedExpr 0x6785a0 '.capture_expr.' 'int'
```
`NoContextC `is of type `OMPNocontextClause *`.
If there is a simpler way to get the OMPCapturedExpr please tell me.

At present, I will rename the function name.
