New Revision: 218383

URL: http://llvm.org/viewvc/llvm-project?rev=218383&view=rev
Log:
Adjust to LLVM JIT API change

Those wrapper functions seems not used by lldb... Removed

Reference for

replacing JITMemoryManager with SectionMemoryManager
replacing "llvm::JITMemoryManager::CreateDefaultMemManager()" with "new llvm::SectionMemoryManager()"
http://llvm.org/viewvc/llvm-project/llvm/trunk/tools/llvm-jitlistener/llvm-jitlistener.cpp?r1=218316&r2=218315&pathrev=218316

Change by Tong Shen.

Tested:
Ubuntu 14.04 x86_64
MacOSX 10.9.5 with Xcode Version 6.1 (6A1030) (Beta)
