1d05cb47a9 add an option to generate completely non-pic code, corresponding to what 
gcc -static produces on PPC.  This is used for building kexts and other things.

With this, materializing the address of a global looks like:

        lis r2, ha16(L_H$non_lazy_ptr)
        la r3, lo16(L_H$non_lazy_ptr)(r2)

we're still emitting stubs for functions, which is wrong.  That is next.

3eef4e377c Enable global address legalization, fixing a todo and allowing the removal 
of some code.  This exposes the implicit load from the stubs to the DAG, allowing
them to be optimized by the dag combiner.  It also moves darwin specific stuff
out of the isel into the legalizer, and allows more to be moved to the .td file.

860e8862c1 Add an initial hack at legalizing GlobalAddress into the appropriate nodes 
on Darwin to remove smarts from the isel.  This is currently disabled by
default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file.  However, we can currently emit stuff like
this:  :)

        li r2, lo16(L_x$non_lazy_ptr)
        lis r3, ha16(L_x$non_lazy_ptr)
        lwzx r2, r3, r2

The obvious improvements will follow.

3787c95e86 * Fix DerivedType::dropAllTypeUses to not change the number of types in a 
type when it gets refined.  This allows us to hash on this crucial value.
* Fix several issues in TypeMap::RefineAbstractType that prevent it from
  handling hash values that change correctly.
* Define hashTypeStructure to not always return 0.  :)

This last part (which depends on the first two) speeds up gccld time on eon
from 3.78s to 2.75s with a release build (a 28% speedup!).  This resolves
PR474.
