Use DataLayout from the module when easily available.
Eventually DataLayoutPass should go away, but for now that is the only easy
way to get a DataLayout in some APIs. This patch only changes the ones that
have easy access to a Module.
One interesting issue with sometimes using DataLayoutPass and sometimes
fetching it from the Module is that we have to make sure they are equivalent.
We can get most of the way there by always constructing the pass with a Module.
In fact, the pass could be changed to point to an external DataLayout instead
of owning one to make this stricter.
Unfortunately, the C api passes a DataLayout, so it has to be up to the caller
to make sure the pass and the module are in sync.

Fix resetting the DataLayout in a Module.
No tool does this currently, but as everything else in a module we should be
able to change its DataLayout.
Most of the fix is in DataLayout to make sure it can be reset properly.
The test uses Module::setDataLayout since the fact that we mutate a DataLayout
is an implementation detail. The module could hold a OwningPtr<DataLayout> and
the DataLayout itself could be immutable.

[XCore] Prefer to word align functions.
The behaviour of the XCore's instruction buffer means that the performance
of the same code sequence can differ depending on whether it starts at a 4
byte aligned address or not. Since we don't model the instruction buffer
in the backend we have no way of knowing for sure if it is beneficial to
word align a specific function. However, in the absence of precise
modelling, it is better on balance to word align functions because:
* It makes a fetch-nop while executing the prologue slightly less likely.
* If we don't word align functions then a small perturbation in one
function can have a dramatic knock on effect. If the size of the function
changes it might change the alignment and therefore the performance of
all the functions that happen to follow it in the binary. This butterfly
effect makes it harder to reason about and measure the performance of

[SROA] Thread the ability to add a pointer-specific name prefix through
the pointer adjustment code. This is the primary code path that creates
totally new instructions in SROA and being able to lump them based on
the pointer value's name for which they were created causes
*significantly* fewer name collisions and general noise in the debug
output. This is particularly significant because it is making it much
harder to track down instability in the output of SROA, as name
de-duplication is a totally harmless form of instability that gets in
the way of seeing real problems.
The new fancy naming scheme tries to dig out the root "pre-SROA" name
for pointer values and associate that all the way through the pointer
formation instructions. Digging out the root is important to prevent the
multiple iterative rounds of SROA from just layering too much cruft on
top of cruft here. We already track the layers of SROAs iteration in the
alloca name prefix. We don't need to duplicate it here.

[SROA] Fix another instability in SROA with respect to the slice
ordering.
The fundamental problem that we're hitting here is that the use-def
chain ordering is *itself* not a stable thing to be relying on in the
rewriting for SROA. Further, we use a non-stable sort over the slices to
arrange them based on the section of the alloca they're operating on.
With a debugging STL implementation (or different implementations in
stage2 and stage3) this can cause stage2 != stage3.
The specific aspect of this problem fixed in this commit deals with the
rewriting and load-speculation around PHIs and Selects. This, like many
other aspects of the use-rewriting in SROA, is really part of the
"strong SSA-formation" that is doen by SROA where it works very hard to
canonicalize loads and stores in *just* the right way to satisfy the
needs of mem2reg[1]. When we have a select (or a PHI) with 2 uses of the
same alloca, we test that loads downstream of the select are
speculatable around it twice. If only one of the operands to the select
needs to be rewritten, then if we get lucky we rewrite that one first
and the select is immediately speculatable. This can cause the order of
operand visitation, and thus the order of slices to be rewritten, to
change an alloca from promotable to non-promotable and vice versa.
The fix is to defer all of the speculation until *after* the rewrite
phase is done. Once we've rewritten everything, we can accurately test
for whether speculation will work (once, instead of twice!) and the
order ceases to matter.
This also happens to simplify the other subtlety of speculation -- we
need to *not* speculate anything unless the result of speculating will
make the alloca fully promotable by mem2reg. I had a previous attempt at
simplifying this, but it was still pretty horrible.
There is actually already a *really* nice test case for this in
basictest.ll, but on multiple STL implementations and inputs, we just
got "lucky". Fortunately, the test case is very small and we can
essentially build it in exactly the opposite way to get reasonable
coverage in both directions even from normal STL implementations.

Permit CMAKE_INSTALL_RPATH to be set on command line
Commit 201921 overrides setting of CMAKE_INSTALL_RPATH via the
command line. Last time this happened we applied another patch
to only set CMAKE_INSTALL_RPATH if already defined (r197825).
This patch does the same thing again, but only for the UNIX
case - we leave APPLE alone as presumably the original committer
is happy with the non-overriding behaviour.

Simplify linking to system libraries
The LLVMSupport library implementation consolidates all dependencies on
system libraries. Move the logic gathering system libraries out of
'cmake/modules/LLVM-Config.cmake' and into 'lib/Support/CMakeLists.txt'.
Use the target_link_libraries() command there to tell CMake about the
link dependencies of the LLVMSupport implementation. CMake will
automatically propagate this to all targets that link LLVMSupport
directly or indirectly.
We still need to build knowledge of system library dependencies into
'llvm-config'. Store the list of libraries needed in a property on
LLVMSupport and teach 'tools/llvm-config/CMakeLists.txt' to retrieve it
from there.
Drop all calls to 'link_system_libs' and 'get_system_libs' from our
CMake code. Replace their implementations with a warning that explains
the calls are no longer necessary. Also drop from 'LLVMConfig.cmake'
the HAVE_* and related variables that were published there only to allow
'get_system_libs' to run outside our build process.

llvm/test/CodeGen/X86/shift-pcmp.ll: Tweak to appease FileCheck. "CHECK-LABEL" doesn't identify labels magically and CHECK-LABEL behaves free from other contexts.
For targeting pecoff, ".def foo" appears before ".short 32".
.def foo;
...
.LCPI0_0:
.short 32
foo:
CHECK-LABEL seeks not from ".short 32" but from the top of the input.

The API expects an ISD opcode, not an IR opcode.
Fixes a regression for R600.

Use relative rpath so that the installation and build dirs are relocatable.
This works by asking cmake to use the "install rpath", but setting that rpath
to be relative.
Thanks a lot to Brad King for the help with CMake!

Switch the LLVM error reporting on the new diagnostic system.
The LLVM diagnostic are now wired-up in clang (since r200931),
thus the user experience will not be impacted by this change
anymore.
