and yea! Saem said "ARRR."

meanwhile, the pinksias and the campfires and the ET forests glowed.

cff96008ac Add bswap, rotl, and rotr nodes 
Add dag combiner code to recognize rotl, rotr
Add ppc code to match rotl

Targets should add rotl/rotr patterns if they have them

5a59c88c17 Fix calls that need to store values in stack slots, to not copy the stack 
pointer.  This allows us to emit stuff like this:

        li r10, 0
        stw r10, 56(r1)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10
        or r6, r10, r10
        or r7, r10, r10
        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

instead of this:

        or r2, r1, r1     ;; Extraneous copy.
        li r10, 0
        stw r10, 56(r2)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10
        or r6, r10, r10
        or r7, r10, r10
        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

wowness.

97638d35a5 Patch #9 from Saem: 
"Cut up the runPasses method into smaller pieces.  The small private
helpers should  be easier to deal with when code shuffling arising
from creating the new specialised batchers, not to mention, they're
much easier to understand.

I inlined them, in case function call overhead would be noticeable --
doubtful."

1ffbbc9ebc Use Evan's outflag stuff to implement V8cmpicc. This allows us to write a 
pattern for SUBCCrr, and makes it trivial to add support for SUBCCri, eliminating
an instruction in the common "setcc X, imm" case.

e42281bcba * Add special entry code main() (to set x87 to 64-bit precision). 
* Allow a register node as SelectAddr() base.
* ExternalSymbol -> TargetExternalSymbol as direct function callee.
* Use X86::ESP register rather than CopyFromReg(X86::ESP) as stack ptr for
  call parmater passing.
