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.

* Rename existing relocations to be more specific

* Add relocations for refernces to non-lazy darwin stubs and implement
them correctly.
With this change, we can correctly references external globals, and now
all but two UnitTests and all but 1 Regression/C tests pass.
More importantly, bugpoint-jit will start giving us useful testcases,
instead of always telling us that references to external globals don't
work :)
