instead of always using ConstantVector.

8833ef03b9 [unwind removal] Remove all of the code for the dead 'unwind' instruction. There
were no 'unwind' instructions being generated before this, so this is in effect
a no-op.

7d5a289f2d Introduce helpers to compute the 32-bit varaints and 64-bit variants of
some architectures. These are useful for interacting with multiarch or

fad4d40f37 Teach GlobalOpt to handle atomic accesses to globals.
* Most of the transforms come through intact by having each transformed load or
store copy the ordering and synchronization scope of the original.
 * The transform that turns a global only accessed in main() into an alloca
(since main is non-recursive) with a store of the initial value uses an
unordered store, since it's guaranteed to be the first thing to happen in main.
(Threads may have started before main (!) but they can't have the address of a
function local before the point in the entry block we insert our code.)
 * The heap-SRoA transforms are disabled in the face of atomic operations. This
can probably be improved; it seems odd to have atomic accesses to an alloca
that doesn't have its address taken.

AnalyzeGlobal keeps track of the strongest ordering found in any use of the
global. This is more information than we need right now, but it's cheap to
compute and likely to be useful.

33756f96d7 Reduce the number of dom queries made by GVN's conditional propagation
logic by half: isOnlyReachableViaThisEdge was trying to be clever and
handle the case of a branch to a basic block which is contained in a
loop.  This costs a domtree lookup and is completely useless due to
GVN's position in the pass pipeline: all loops have preheaders at this
point, which means it is enough for isOnlyReachableViaThisEdge to check
that Dst has only one predecessor.  (I checked this theoretical argument
by running over the entire nightly testsuite, and indeed it is so!).

69f44692bf Begin fleshing out more convenience predicates in llvm::Triple and
convert at least one client over to use them. Subsequent patches both to
LLVM and Clang will try to convert more people over to a common set of
predicates.

This round of predicates is focused on OS-categorization predicates.
