Kostya Serebryany 9e0d377400 The patch resolves the conflict between AddressSanitizer and load widening (GVN).
The problem initially reported by Mozilla folks (http://code.google.com/p/address-sanitizer/issues/detail?id=20),
but it also prevents us from enabling LLVM bootstrap with AddressSanitizer.

Jakob Stoklund Olesen 769de20ae9 Remove some unused functions.
LiveIntervalAnalysis has a number of functions that simply forward to
SlotIndexes.  Since SlotIndexes is a stand-alone analysis now, clients
should really refer to it directly.

We have automatic local renumbering now.

This CL delays reading of function bodies from initial parse until
materialization, allowing overlap of compilation with bitcode download.

Bill Wendling 0aef16afd5 [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.

Nick Lewycky 52da72b12a 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.

Duncan Sands 4b613497f0 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!).

Duncan Sands 268903955c Reduce the number of non-trivial domtree queries by about 1% when
