Several important bug fixes:

(1) Cannot use ANDN(ot), ORN, and XORN for boolean ops, only bitwise ops.

(2) Conditional move instructions must distinguish signed and unsigned
    condition codes, e.g., MOVLE vs. MOVLEU.

(3) Conditional-move-on-register was using the cond-move-on-cc opcodes,
    which produces a valid-looking instruction with bogus registers!

(4) Here's a really cute one: dividing-by-2^k for negative numbers needs to
    add 2^k-1 before shifting, not add 1 after shifting.  Sadly, these
    are the same when k=0 so our poor test case worked fine.

(5) Casting between signed and unsigned values was not correct:
    completely reimplemented.

(6) Zero-extension on unsigned values was bogus: I was only doing the
    SRL and not the SLLX before it.  Don't know WHAT I was thinking!

(7) And the most important class of changes: Sign-extensions on signed values.
    Signed values are not sign-extended after ordinary operations,
    so they must be sign-extended before the following cases:
-- passing to an external or unknown function
-- returning from a function
-- using as operand 2 of DIV or REM
-- using as either operand of condition-code setting operation
           (currently only SUBCC), with smaller than 32-bit operands

Also, a couple of improvements:

(1) Fold cast-to-bool into Not(bool).  Need to do this for And, Or, XOR also.

(2) Convert SetCC-Const into a conditional-move-on-register (case 41)
    if the constant is 0.  This was only being done for branch-on-SetCC-Const

    even if no other "neighbour" in the interf. graph has been allocated
    that reg. yet.  This is actually true of any class with only one reg!

(2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must
    be spilled so that the machine-independent spill code doesn't have to
    make the machine-dependent decision of which CC name to use based on
    operand type: %xcc or %icc.  (These are two halves of the same
register.)

(3) LR->isMarkedForSpill() is no longer the same as LR->hasColor().
    These should never have been the same, and this is necessary now for #2.

(4) All RDCCR and WRCCR instructions are directly generated with the
