d89ddc118c Revert "Adding object caching support to MCJIT"
This reverts commit 07f03923137a91e3cca5d7fc075a22f8c9baf33a.

Looks like it broke the valgrind bot:

5f190b5e4e Introduce llvm::sys::getProcessTriple() function.
In r143502, we renamed getHostTriple() to getDefaultTargetTriple()
as part of work to allow the user to supply a different default
target triple at configure time.  This change also affected the JIT.
However, it is inappropriate to use the default target triple in the
JIT in most circumstances because this will not necessarily match
the current architecture used by the process, leading to illegal
instruction and other such errors at run time.

Introduce the getProcessTriple() function for use in the JIT and
its clients, and cause the JIT to use it.  On architectures with a
single bitness, the host and process triples are identical.  On other
architectures, the host triple represents the architecture of the
host CPU, while the process triple represents the architecture used
by the host CPU to interpret machine code within the current process.
For example, when executing 32-bit code on a 64-bit Linux machine,
the host triple may be 'x86_64-unknown-linux-gnu', while the process
triple may be 'i386-unknown-linux-gnu'.

This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple
platforms.

4c1f3c24db Move all of the header files which are involved in modelling the LLVM IR
into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.

There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.

The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.

I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).

I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

ca8d63b46f 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.

e6c3b1a551 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.
