Enable rematerialization of constants using AliasAnalysis::pointsToConstantMemory,
...
and knowledge of PseudoSourceValues. This unfortunately isn't sufficient to allow
constants to be rematerialized in PIC mode -- the extra indirection is a
complication.

Include a frame index in the "fixed stack" pseudo source value
...
instead of using the frame index for the SVOffset, which was
inconsistent.

A quick nm audit turned up several fixed tables and objects that were
...
marked read-write. Use const so that they can be allocated in a
read-only segment.

Follow Chris' suggestion; change the PseudoSourceValue accessors
...
to return pointers instead of references, since this is always what
is needed.

Re-apply the memory operand changes, with a fix for the static
...
initializer problem, a minor tweak to the way the
DAGISelEmitter finds load/store nodes, and a renaming of the
new PseudoSourceValue objects.

Add a new PseudoSourceValue class, which will be used to help track
...
memory reference information in the backend. Most of this was written by
Florian Brander, cleanup and updating to TOT by me.
