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.

* 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.)

restore %g0, %g0, %g0

emit this:

save %o6, %g1, %o6
sethi 4194264, %g1
add %g1, %i6, %g1
