e4a97f4bee If a global is just loaded and restored, realize that it is not changing 
value.  This allows us to turn more globals into constants and eliminate them.
This patch implements GlobalOpt/load-store-global.llx.

Note that this patch speeds up 255.vortex from:

Output/255.vortex.out-cbe.time:program 7.640000
Output/255.vortex.out-llc.time:program 9.810000

to:

Output/255.vortex.out-cbe.time:program 7.250000
Output/255.vortex.out-llc.time:program 9.490000

Which isn't bad at all!

3d61b688a9 This optimization makes MANY phi nodes that all have the same incoming value. 
If this happens, detect it early instead of relying on instcombine to notice
it later.  This can be a big speedup, because PHI nodes can have many
incoming values.

1e4cad9176 Implement instcombine/phi.ll:test6 - pulling operations through PHI nodes. 
This exposes subsequent optimization possiblities and reduces code size.
This triggers 1423 times in spec.

fe6c85da57 New testcase: the phi can be eliminated if the casts are sucked into it. 
Note that this reduces code size anyway (as well as making further
optimizations simpler) so it's always a win.

fdd41995d8 Transform this: 
%X = alloca ...
  %Y = alloca ...
    X == Y

into false.  This allows us to simplify some stuff in eon (and probably
many other C++ programs) where operator= was checking for self assignment.
Folding this allows us to SROA several additional structs.

363e78c357 If a function always returns a constant, replace all calls sites with that 
constant value.  This makes the return value dead and allows for
simplification in the caller.

This implements IPConstantProp/return-constant.ll

This triggers several dozen times throughout SPEC.

d0a0af0818 Teach SROA how to promote an array index that is variable, if the dimension 
of the array is just two.  This occurs 8 times in gcc, 6 times in crafty, and
12 times in 099.go.

This implements ScalarRepl/sroa_two.ll

9749bf21f8 Argument promotion transforms functions to unconditionally load their 
argument pointers.  This is only valid to do if the function already
unconditionally loaded an argument or if the pointer passed in is known
to be valid.  Make sure to do the required checks.

This fixed ArgumentPromotion/control-flow.ll and the Burg program.
