6656dd1a78 Handle physreg input/outputs. We now compile this: 
int %test_cpuid(int %op) {
        %B = alloca int
        %C = alloca int
        %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
        %Cv = load int* %C
        %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.

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.

8137c9e41d Eliminate the need for ExpandOp to set 'needsanotheriteration', as it already 
relegalizes the stuff it returns.

Add the ability to custom expand ADD/SUB, so that targets don't need to deal
with ADD_PARTS/SUB_PARTS if they don't want.

Fix some obscure potential bugs and simplify code.

preference to determine which scheduler to use. SchedulingForLatency ==
Breadth first; SchedulingForRegPressure == bottom up register reduction list
scheduler.

0b118206bf For PR411: 
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
  llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
  llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
  llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
  llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
  llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.
