SPARC condition codes, not in terms of the DAG condcodes.  This allows us to
write nice clean patterns for cmovs/branches.

uint %test(uint %X) {
        %Y = call uint %llvm.ctpop.i32(uint %X)
        ret uint %Y
}

to:

test:
        save -96, %o6, %o6
        sll %i0, 0, %l0
        popc %l0, %i0
        restore %g0, %g0, %g0
        retl
        nop

instead of to 40 logical ops.  Note the shift-by-zero that clears the top
part of the 64-bit V9 register.

patterns.  This allows emission of this code:

t1:
        save -96, %o6, %o6
        subcc %i0, %i1, %l0
        move %icc, %i0, %i2
        or %g0, %i2, %i0
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

t1:
        save -96, %o6, %o6
        subcc %i0, %i1, %l0
        be .LBBt1_2     !
        nop
.LBBt1_1:       !
        or %g0, %i2, %i0
.LBBt1_2:       !
        restore %g0, %g0, %g0
        retl
        nop

for this:

int %t1(int %a, int %b, int %c) {
        %tmp.2 = seteq int %a, %b
        %tmp3 = select bool %tmp.2, int %a, int %c
        ret int %tmp3

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.

* 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.)
