Nate Begeman d4c8bea47f Enable optimization suggested by Chris Lattner to not emit reloc stubs for 
static global variables whose addresses are taken.  This allows us to
convert the following code for taking the address of a static function foo

        addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")
        lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2)

which also includes linker stub code emitted at the end of the .s file not
shown here, and replace it with this:

        addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb")
        la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2)

which in addition to not needing linker help, also has no load instruction.
For those not up on PowerPC mnemonics, la is shorthand for add immediate.
