0b06d57ccd Add support for a few simple fixups to the ARM Darwin asm backend. This allows 
constant pool references and global variable refernces to resolve properly
for object file generation. For example,

int x;
void foo(unsigned a, unsigned *p) {
  p[a] = x;
}

can now be successfully compiled directly to an (ARM mode) object file.

a5c69eec12 Fix PR8441, a race condition in the static attributes list. While the reference counting was itself threadsafe, 
the implicit removal of each object from the global list was not.  Make this operation atomic.

45ec210e3c Adds support for spilling previously allocated live intervals to 
handle cases in which a register is unavailable for spill code.
Adds LiveIntervalUnion::extract. While processing interferences on a
live virtual register, reuses the same Query object for each
physcial reg.

6909ecf66e Extend the AliasAnalysis::pointsToConstantMemory interface to allow it 
to optionally look for constant or local (alloca) memory.

Teach BasicAliasAnalysis::pointsToConstantMemory to look through Select
and Phi nodes, and to support looking for local memory.

Remove FunctionAttrs' PointsToLocalOrConstantMemory function, now that
AliasAnalysis knows all the tricks that it knew.

getModRefBehavior now, since it now understands intrinsics as well
as normal functions.
