4183d7faf3 Reserve space in these vectors to prevent having to grow the array too 
much. This gets us an addition 0.9% on 445.gobmk.

3e1478c558 This is a small patch with a couple of improvements for running lit with --debug: 
1. Added a status note when a config file is loaded directly with load_config. This helps notice loads of lit.cfg from lit.site.cfg
2. Added a status note on the result of a config load. Previously, it was just notifying that it tries to load a config file. Now it will also say whether the load succeeded or the file wasn't found

The two changes give better visibility into which config files were actually loaded by lit. The effect is only on --debug runs.

Patch by Eli Bendersky!

f4be131943 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.

d0be5953be 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.

f522835510 Enable streaming of bitcode 
This CL delays reading of function bodies from initial parse until
materialization, allowing overlap of compilation with bitcode download.

were no 'unwind' instructions being generated before this, so this is in effect

bad48a142a 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.
