When computing the index expressions for new, multi-dimensional memory accesses
these new index expressions may reference original llvm::Values that are not
transfered into the OpenMP subfunction. Using GlobalMap we now replace
references to such values with the rewritten values that have e.g. been passed
to the OpenMP subfunction.

The GlobalMap variable used in BlockGenerator should always reference the same
list througout the entire code generation, hence we can make it a member
variable to avoid passing it around through every function call.

History: Before we switched to the SCEV based code generation the GlobalMap
also contained a mapping form old to new induction variables, hence it was
different for each ScopStmt, which is why we passed it as function argument
to copyStmt. The new SCEV based code generation now uses a separate mapping
called LTS -> LoopToSCEV that maps each original loop to a new loop iteration
variable provided as a SCEVExpr. The GlobalMap is currently mostly used for
OpenMP code generation, where references to parameters in the original function
need to be rewritten to the locations of these variables after they have been
passed to the subfunction.

Summary:
This diff attempts to address the concerns raised in
http://reviews.llvm.org/D12488.

We introduce a new USE_SHARED option to llvm_config,
which, if set, causes the target to be linked against
libLLVM.

add_llvm_utility now uniformly disables linking against
libLLVM. These utilities are not intended for distribution,
and this keeps the option handling more centralised.

llvm-shlib is now processes before any other "tools"
subdirectories, ensuring the libLLVM target is defined
before its dependents.

One main difference from what was requested: llvm_config
does not prune LLVM_DYLIB_COMPONENTS from the components
passed into explicit_llvm_config. This is because the "all"
component does something special, adding additional
libraries (namely libLTO). Adding the component libraries
after libLLVM should not be a problem, as symbols will be
resolved in libLLVM first.

Finally, I'm not really happy with the
DISABLE_LLVM_LINK_LLVM option, but I'm not sure of a
better way to get the following:
 - link all tools and shared libraries to libLLVM if
   LLVM_LINK_LLVM_DYLIB is set
 - some way of explicitly *not* doing so for utilities
   and libLLVM itself
Suggestions for improvement here are particularly welcome.

Originally, we disallowed the import of multi-dimensional access functions due
to our code generation not supporting the generation of new address expressions
for multi-dimensional memory accesses. When building our run-time alias check
infrastructure we added code generation support for multi-dimensional address
calculations.  Hence, we can now savely allow the import of new
multi-dimensional access functions.

We want a deterministic output. GNU AS leaves it zero.

This commit accomplish two goals:
1) it's a step forward to deprecate macho-dump, now less than 40 tests
rely on it.

2) It tests all the MachO specific features introduced in llvm-readobj in
the following commits:  r246789, r246665, r246474.

While the conversion is mostly mechanical (I double-checked all the
tests output one by one, but still), a post-commit review is greatly
appreciated.

PPCISelDAGToDAG has a transformation that generates a rlwimi instruction from
an input pattern that looks like this:

  and(or(x, c1), c2)

but the associated logic does not work if there are bits that are 1 in c1 but 0
in c2 (these are normally canonicalized away, but that can't happen if the 'or'
has other users. Make sure we abort the transformation if such bits are
discovered.

Fixes PR24704.

Tests need to be run either via asanwrapper or asanwrapper64
depending in the binary bitness. This matters when testing on an
aarch64 device.

Apparently there are many cast kinds that may cause implicit pointer
arithmetic to happen. In light of this, the cast ignoring logic
introduced in r246877 has been changed to only ignore a small set of
cast kinds, and a test for this behavior has been added.

Thanks to Richard for catching this before it became a bug report. :)
