26d4fdb968 Fix a minor bug (ORo didn't mark that it set CR0). 
Refactor how . instructions are handled.  In particular, instead of passing
the RC flag all the way up the inheritance hierarchy, just make a new tblgen
class 'DOT' which can be added to an instruction definition.

For example, instead of this:

-def AND  : XForm_6<31,  28, 0, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
-let Defs = [CR0] in
-def ANDo : XForm_6<31,  28, 1, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
-                   "and. $rA, $rS, $rB">;

We now have this:

+def AND  : XForm_6<31,  28, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
                    "and $rA, $rS, $rB">;

5ef2ec9929 assorted fixes: 
* clean up immediates (we use 14, 22 and 64 bit immediates now. sane.)
  * fold r0/f0/f1 registers into comparisons against 0/0.0/1.0
  * fix nasty thinko - didn't use two-address form of conditional add
    for extending bools to integers, so occasionally there would be
    garbage in the result. it's amazing how often zeros are just
    sitting around in registers ;) - this should fix a bunch of tests.

51d2ed976f rename getPPCOpcodeForSetCCNumber -> getPPCOpcodeForSetCCOpode to be more 
correct.  Remove the EmitComparison retvalue, as it is always the first arg.

Fix a place where we incorrectly passed in the setcc opcode instead of the
setcc number, causing us to miscompile crafty.  Crafty now works!

e00e5ded51 ok, the "ia64 has a boatload of registers" joke stopped being funny today ;) 
* fix overallocation of integer (stacked) registers: we can't allocate
  registers for local use if they are required as output registers

this fixes 'toast' in the test suite, and all sorts of larger programs
like bzip2 etc.
