927ba6a0b3 Moving SectionMemoryManager into RuntimeDyld and adding unit tests for it. 
The SectionMemoryManager now supports (and requires) applying section-specific page permissions.  Clients using this memory manager must call either MCJIT::finalizeObject() or SectionMemoryManager::applyPermissions() before executing JITed code.

See r168718 for changes from the previous implementation.

cc7773bdcb Implementing page permission setting in MCJIT unit test SectionMemoryManager.cpp 
This commit is primarily here for the revision history.  I'm about to move the SectionMemoryManager into the RuntimeDyld library, but I wanted to check the changes in here so people could see the differences in the updated implementation.
