Initial submission for the attribute group feature.
Attribute groups are of the form:
#0 = attributes { noinline "no-sse" "cpu"="cortex-a8" alignstack=4 }
Target-dependent attributes are represented as strings. Attributes can have
optional values associated with them. E.g., the "cpu" attribute has the value
"cortex-a8".
Target-independent attributes are listed as enums inside the attribute classes.
Multiple attribute groups can be referenced by the same object. In that case,
the attributes are merged together.

For example, ARM has several instructions with a literal '#0' immediate in the syntax
that's not represented as an actual operand. The asm matcher is expected a token

Reapply r174343, with a fix for a scary DAG combine bug where it failed to differentiate between the alignment of the
base point of a load, and the overall alignment of the load. This caused infinite loops in DAG combine with the
original application of this patch.
ORIGINAL COMMIT LOG:
When the target-independent DAGCombiner inferred a higher alignment for a load,
it would replace the load with one with the higher alignment. However, it did
not place the new load in the worklist, which prevented later DAG combines in
the same phase (for example, target-specific combines) from ever seeing it.
This patch corrects that oversight, and updates some tests whose output changed
due to slightly different DAGCombine outputs.

[MC] Bundle alignment: Invalidate relaxed fragments
Currently, when a fragment is relaxed, its size is modified, but its
offset is not (it gets laid out as a side effect of checking whether
it needs relaxation), then all subsequent fragments are invalidated
because their offsets need to change. When bundling is enabled,
relaxed fragments need to get laid out again, because the increase in
size may push it over a bundle boundary. So instead of only
invalidating subsequent fragments, also invalidate the fragment that
gets relaxed, which causes it to get laid out again.
This patch also fixes some trailing whitespace and fixes the
bundling-related debug output of MCFragments.

Don't use MRI liveouts in R600.
Something very strange is going on with the output registers in this
target. Its ISelLowering code is inserting dangling CopyToReg nodes,
hoping that those physregs won't get clobbered before the RETURN.
This patch adds the output registers as implicit uses on RETURN
instructions in the custom emission pass. I'd much prefer to have those
CopyToReg nodes glued to the RETURNs, but I don't see how.

Loop Vectorizer: Handle pointer stores/loads in getWidestType()
In the loop vectorizer cost model, we used to ignore stores/loads of a pointer
type when computing the widest type within a loop. This meant that if we had
only stores/loads of pointers in a loop we would return a widest type of 8bits
(instead of 32 or 64 bit) and therefore a vector factor that was too big.
Now, if we see a consecutive store/load of pointers we use the size of a pointer
(from data layout).
This problem occured in SingleSource/Benchmarks/Shootout-C++/hash.cpp (reduced
test case is the first test in vector_ptr_load_store.ll).
