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.

bae5b3c1c6 LI could theoretically be used for the lo-part of a global address, just like 
lis can be used for the high part.

2823b3e70e 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.

preventing labels like LBB"foo"_2.
