When uniquing classes against one another we can't depend on any or all of the artificial functions (default ctor, dtor, copy ctor, move ctor, etc) being in each definition. Now we treat those separately and handle those to the best of our ability.

The old checking code, which assumed that input shuffles and insert-elements
could always be folded (and thus were free) is too simple.
This can only happen in special circumstances.
Using the simple check caused infinite recursion.

Per discussion on cfe-dev, re-enable suppression of -Wimplicit-fallthrough on C, but also include dialects of C++ earlier than C++11.

There was enough consensus that we *can* get a good language solution
to have an annotation outside of C++11, and without this annotation
this warning doesn't quite mean's completeness criteria for this
kind of warning.  For now, restrict this warning to C++11 (where an
annotation exists), and make this the behavior for the LLVM 3.2 release.
Afterwards, we will hammer out a language solution that we are all
happy with.

Uses the infrastructure from r167742 to support clustering instructure
that the target processor can "fuse". e.g. cmp+jmp.

Next step: target hook implementations with test cases, and enable.

The pass would previously assert when trying to compute the cost of
compare instructions with illegal vector types (like struct pointers).

This infrastructure is generally useful for any target that wants to
strongly prefer two instructions to be adjacent after scheduling.

A following checkin will add target-specific hooks with unit
tests. Then this feature will be enabled by default with misched.

The assertion is trigged when the Reassociater tries to transform expression
     ... + 2 * n * 3 + 2 * m + ...
  into:
     ... + 2 * (n*3 + m).

In the process of the transformation, a helper routine folds the constant 2*3 into 6,
confusing optimizer which is trying the to eliminate the common factor 2, and cannot
find 2 any more. 

Review is pending. But I'd like commit first in order to help those who are waiting 
for this fix.

This fixes a bug where shuffles were being fused such that the
resulting input types were not legal on the target. This would
occur only when both inputs and dependencies were also foldable
operations (such as other shuffles) and there were other connected
pairs in the same block.

Fixup for r167558: Store raw pointer (instead of reference) to RelocMap in DIContext. This is needed to prevent crashes because of dangling reference if the clients don't provide RelocMap to DIContext constructor.

The library call simplifier folds memcmp calls with all constant arguments
to a constant.  For example:

  memcmp("foo", "foo", 3) ->  0
  memcmp("hel", "foo", 3) ->  1
  memcmp("foo", "hel", 3) -> -1

The folding is implemented in terms of the system memcmp that LLVM gets
linked with.  It currently just blindly uses the value returned from
the system memcmp as the folded constant.

This patch normalizes the values returned from the system memcmp to
(-1, 0, 1) so that we get consistent results across multiple platforms.
The test cases were adjusted accordingly.

The 'a', 'c', and 'd' constraints on i386 mean a 32-bit register. We cannot
