While we're at it, improve codegen of select instructions. For this
testcase:
int %test(bool %C, int %A, int %B) {
%D = select bool %C, int %A, int %B
ret int %D
}
We used to generate this code:
_test:
cmpwi cr0, r3, 0
bne .LBB_test_2 ;
.LBB_test_1: ;
b .LBB_test_3 ;
.LBB_test_2: ;
or r5, r4, r4
.LBB_test_3: ;
or r3, r5, r5
blr
Now we emit:
_test:
cmpwi cr0, r3, 0
bne .LBB_test_2 ;
.LBB_test_1: ;
or r4, r5, r5
.LBB_test_2: ;

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.

the constant pool yet).
