------- Additional Comments from Filip Pizlo <fpizlo at apple.com>
Includes beginnings of proper ARMv7 support in the offlineasm backend. This is
done by doing a series of micropasses that break down the larger operations
(like say "addi 5000, 4[foo, bar, 8]") into smaller ones ("move 4, tmp1; addp
foo, tmp1; loadi [tmp1, bar, 8], tmp2; move 5000, tmp3; addi tmp3, tmp2; storei
tmp2, [tmp1, bar, 8]").

Also includes a build fix in tools/; I'll land that build fix separately and
exclude it from this patch in the next rebase.
