Fix several bugs in 'op x, imm' handling. Foremost is that we now emit
...
addi r3, r3, -1
instead of
addi r3, r3, 1
for 'sub int X, 1'.
Secondarily, this fixes several cases where we could crash given an unsigned
constant. And fixes a couple of minor missed optimization cases, such as
xor X, ~0U -> not X

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.

With this change, we can correctly references external globals, and now

Fix Shootout-C++/wc, which was broken by my recent changes to emit fewer
...
reg-reg copies. The necessary conditions for this bug are a GEP that is
used outside the basic block in which it is defined, whose components
other than the pointer are all constant zero, and where the use is
selected before the definition (backwards branch to successsor block).
