Changes in IntelJITEventListener - By Arch Robinson

- take->release: LLVM has moved to C++11.  MockWrapper became an instance of unique_ptr.

   - method symbol_iterator::increment disappeared recently, in this revision:

     r200442 | rafael | 2014-01-29 20:49:50 -0600 (Wed, 29 Jan 2014) | 9 lines

Simplify the handling of iterators in ObjectFile.

None of the object file formats reported error on iterator increment. In
retrospect, that is not too surprising: no object format stores symbols or
sections in a linked list or other structure that requires chasing pointers.
As a consequence, all error checking can be done on begin() and end().

This reduces the text segment of bin/llvm-readobj in my machine from 521233 to
518526 bytes.

My change mimics the change that the revision made to lib/DebugInfo/DWARFContext.cpp .

    - const_cast: Shut up a warning from gcc.

I ran unittests/ExecutionEngine/JIT/Debug+Asserts/JITTests to make sure it worked.
