8d04987a39 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.

5f605f3c12 LI could theoretically be used for the lo-part of a global address, just like 
lis can be used for the high part.

7fdf96ed96 When lowering direct calls, lower them to use a targetglobaladress directly 
instead of a globaladdress.  This has no effect on the generated code at all.

d69b86453a * 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.

6e3f8ee849 Separate the type-became-concrete case from the type-is-resolved case, the 
former of which takes much less work than the later.  This speeds up linking
eon from 3.749 to 3.637s with a release build (about 3%).
