2b4ea795a2 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

171049d10f * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead. 
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)

to represent the int part (because it's always 32-bits)

2cfdbb2716 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

into this:

test:

        xor %l0, 123, %i0
        restore %g0, %g0, %g0
        retl
        nop

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