47785d8fc3 Add initial conditional branch support. This doesn't actually work yet due 
to a bug in the scheduler.

a17cbf352e add andn/orn/xorn patterns. This allows us to compile this: 
long %test(ubyte, short, long %X, long %Y) {
  %A = xor long %X, -1
  %B = and long %Y, %A
  ret long %B
}

to this:

test:
        save -96, %sp, %sp
        andn %i4, %i2, %i0
        andn %i5, %i3, %i1
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

test:
        save -96, %sp, %sp
        xor %i2, -1, %l0
        xor %i3, -1, %l1
        and %i4, %l0, %i0
        and %i5, %l1, %i1
        restore %g0, %g0, %g0
        retl
        nop

The simpleisel emits:  :(

test:
        save -96, %sp, %sp
        or %g0, -1, %l0
        or %g0, -1, %l0
        or %g0, -1, %l0
        or %g0, -1, %l1
        xor %i2, %l0, %l0
        xor %i3, %l1, %l1
        and %i4, %l0, %i0
        and %i5, %l1, %i1
        restore %g0, %g0, %g0
        retl
        nop

56649f9616 Darwin API issue: indirect load of external and weak symbols.

2ba4a8584c Add some simple integer patterns. This allows us to compile this: 
int %test(int %A) {
  %B = add int %A, 1
  %C = xor int %B, 123
  ret int %C
}

into this:

test:
        save -96, %sp, %sp
        add %i0, 1, %l0
        xor %l0, 123, %i0
        restore %g0, %g0, %g0
        retl
        nop

for example.  I guess it would make sense to add reg/reg versions too.

91e36127ed Use the AsmPrinter for global variable init printing. This eliminates a 
bunch of code and causes V8 to start using the fancy .asciz directive that
the sun assembler supports.
