2cc2f66c25 adjust to changes in InlineAsm interface. Fix a few minor bugs.

760df29881 Return's chain should be matching either the chain produced by the 
value or the chain going into the load.

0d084c9e4a When folding a load into a return of SSE value, check the chain to 
ensure the memory location has not been clobbered.

6656dd1a78 Handle physreg input/outputs. We now compile this:

        %D = alloca int
        %A = call int asm "cpuid", "=eax,==ebx,==ecx,==edx,eax"(int* %B, int* %C, int* %D, int %op)
        %Bv = load int* %B

        %Dv = load int* %D
        %x = add int %A, %Bv
        %y = add int %x, %Cv
        %z = add int %y, %Dv
        ret int %z
}

to this:

_test_cpuid:
        sub %ESP, 16
        mov DWORD PTR [%ESP], %EBX
        mov %EAX, DWORD PTR [%ESP + 20]
        cpuid
        mov DWORD PTR [%ESP + 8], %ECX
        mov DWORD PTR [%ESP + 12], %EBX
        mov DWORD PTR [%ESP + 4], %EDX
        mov %ECX, DWORD PTR [%ESP + 12]
        add %EAX, %ECX
        mov %ECX, DWORD PTR [%ESP + 8]
        add %EAX, %ECX
        mov %ECX, DWORD PTR [%ESP + 4]
        add %EAX, %ECX
        mov %EBX, DWORD PTR [%ESP]
        add %ESP, 16
        ret

... note the proper register allocation.  :)

it is unclear to me why the loads aren't folded into the adds.

76afdc9a80 First step towards V9 instructions in the V8 backend, two conditional move 
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

dea9528f7f When lowering SELECT_CC, see if the input is a lowered SETCC. If so, fold 
the two operations together.  This allows us to compile this:

void %two(int %a, int* %b) {
        %tmp.2 = seteq int %a, 0
        %tmp.0.0 = select bool %tmp.2, int 10, int 20
        store int %tmp.0.0, int* %b
        ret void
}

into:

two:
        save -96, %o6, %o6
        or %g0, 20, %l0
        or %g0, 10, %l1
        subcc %i0, 0, %l2

        or %g0, %l0, %l1

        st %l1, [%i1]
        restore %g0, %g0, %g0

instead of:

c52ad4f04e Use the new "UpdateNodeOperands" method to simplify LegalizeDAG and make it 
faster.  This cuts about 120 lines of code out of the legalizer (mostly code
checking to see if operands have changed).

It also fixes an ugly performance issue, where the legalizer cloned the entire
graph after any change.  Now the "UpdateNodeOperands" method gives it a chance
to reuse nodes if the operands of a node change but not its opcode or valuetypes.

This speeds up instruction selection time on kimwitu++ by about 8.2% with a
release build.

456a93afce Several major changes: 
1. Pull out the expand cases for BSWAP and CT* into a separate function,
   reducing the size of LegalizeOp.
2. Fix a bug where expand(bswap i64) was wrong when i64 is legal.
3. Changed LegalizeOp/PromoteOp so that the legalizer never needs to be
   iterative.  It now operates in a single pass over the nodes.
4. Simplify a LOT of code, with a net reduction of ~280 lines.

b0636041c8 fix stack corruption! Previously, 16-byte whole-FP-register stores were 
being treated as needing only 8 bytes (though they were 16 byte aligned.)

This should fix a bunch of tests - anyone have any comments, though?

  - in Target.td , SpillSize and SpillAlignment seem dead - is this what
    Size and Alignment do now?
  - in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and
    DeclaredSpillAlignment seem dead.
  - there are a bunch of comments here and there that don't clearly
    distinguish between 'size' and 'spillsize' etc. hmm.
