Chandler Carruth 8b67f774e9 Move DataTypes.h to include/llvm/System, update all users. This breaks the last 
direct inclusion edge from System to Support.

Reid Kleckner 10b4fc552f Re-committing r76828 with the JIT memory manager changes now that the build 
bots like the BumpPtrAllocator changes.

Reid Kleckner 4bf370698a Reverting r76825 and r76828, since they caused clang runtime errors and some build failure involving memset.

Reid Kleckner 81ce3ed08c Make the JIT code emitter properly retry and ask for more memory when it runs 
out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

Jim Grosbach 932a32d251 Update the stub and callback code to handle lazy compilation. The stub 
is re-written by the callback to branch directly to the compiled code
in future invocations.

Added back in range-based memory permission functions for the updating of
the stub on Darwin.

Jim Grosbach cce6c297c5 On Darwin ARM, memory needs special handling to do JIT. This patch expands 
this handling to work properly for modifying stub functions, relocations
back to entry points after JIT compilation, etc..

Reid Spencer 7107c3badf For PR780: 
1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore
