6f4a072e1f Rename BSel -> PPCBSel for the benefit of doxygen users. 
Move the methods out of line.
Remove unused Debug.h stuff.
Teach getNumBytesForInstruction to know the size of an inline asm.

7560c3af83 Simplify some code, reducing calls to MaskedValueIsZero. Implement a minor 
optimization where we reduce the number of bits in AND masks when possible.

9ca96410fc Use EraseInstFromFunction in a few cases to put the uses of the removed 
instruction onto the worklist (in case they are now dead).

Add a really trivial local DSE implementation to help out bitfield code.
We now fold this:

struct S {
    unsigned char a : 1, b : 1, c : 1, d : 2, e : 3;
    S();
};

S::S() : a(0), b(0), c(1), d(0), e(6) {}

to this:

void %_ZN1SC1Ev(%struct.S* %this) {
entry:
        %tmp.1 = getelementptr %struct.S* %this, int 0, uint 0
        store ubyte 38, ubyte* %tmp.1
        ret void
}

much earlier (in gccas instead of only in gccld after DSE runs).

74c51a0ff2 Generalize MaskedValueIsZero into a ComputeMaskedNonZeroBits function, which 
is just as efficient as MVIZ and is also more general.

Fix a few minor bugs introduced in recent patches

3bedbd9d71 Make MaskedValueIsZero take a uint64_t instead of a ConstantIntegral as a 
mask.  This allows the code to be simpler and more efficient.

Also, generalize some of the cases in MVIZ a bit, making it slightly more aggressive.

8c9191c644 The interpreter assumes that the caller of runFunction() must be lli, and 
therefore the function being called must be a main() returning an int.  The
consequences when these assumptions are false are not good, so don't assume
them.

the interpreter can already handle new functions being added.

221fc3c6d6 Fix two significant bugs in LSR: 
1. When rewriting code in outer loops, sometimes we would insert code into
   inner loops that is invariant in that loop.
2. Notice that 4*(2+x) is 8+4*x and use that to simplify expressions.

This is a performance neutral change.

69d39091fe Two changes: 
1. Treat FMOVD as a copy instruction, to help with coallescing in V9 mode
2. When in V9 mode, insert FMOVD instead of FpMOVD instructions, as we don't
   ever rewrite FpMOVD instructions into FMOVS instructions, thus we just end
   up with commented out copies!
This should fix a bunch of failures in V9 mode on sparc.

store EAX -> [ss#0]
[ss#0] += 1

use(EAX)

In this case, it is not valid to rewrite this as:


store EAX -> [ss#0]
EAX += 1
store EAX -> [ss#0]  ;;; this would also delete the store above
...
use(EAX)

... because EAX is not a dead at that point.  Keep track of which registers
we are allowed to clobber, and which ones we aren't, and don't clobber the
ones we're not supposed to.  :)

1118d25d39 Add code that checks for noop copies, which triggers when either: 
1. a target doesn't know how to fold load/stores into copies, or
2. the spiller rewrites the input to a copy to the same register as the dest
   instead of to the reloaded reg.

This will be moved/improved in the near future, but allows elimination of
some ancient x86 hacks.  This eliminates 92 copies from SMG2000 on X86 and
163 copies from 252.eon.

07cf14112d Physregs may hold multiple stack slot values at the same time. Keep track 
of this, and use it to our advantage (bwahahah).  This allows us to eliminate another
60 instructions from smg2000 on PPC (probably significantly more on X86).  A common
old-new diff looks like this:

        stw r2, 3304(r1)
-       lwz r2, 3192(r1)
        stw r2, 3300(r1)

-       lwz r2, 3192(r1)
        stw r2, 3196(r1)
-       lwz r2, 3192(r1)
+       or r2, r2, r2
        stw r2, 3188(r1)

and

-       lwz r31, 604(r1)
-       lwz r13, 604(r1)
-       lwz r14, 604(r1)
-       lwz r15, 604(r1)
-       lwz r16, 604(r1)

cd81639d2e Fix a deficiency in the spiller that Evan noticed. In particular, consider 
this code:

  store [stack slot #0],  R10
    = add R14, [stack slot #0]

The spiller didn't know that the store made the value of [stackslot#0] available
in R10 *IF* the store came from a copy instruction with the store folded into it.

This patch teaches VirtRegMap to look at these stores and recognize the values
they make available.  In one case Evan provided, this code:

        divsd %XMM0, %XMM1
        movsd %XMM1, QWORD PTR [%ESP + 40]
1)      movsd QWORD PTR [%ESP + 48], %XMM1
2)      movsd %XMM1, QWORD PTR [%ESP + 48]
        addsd %XMM1, %XMM0
3)      movsd QWORD PTR [%ESP + 48], %XMM1
        movsd QWORD PTR [%ESP + 4], %XMM0

turns into:

        divsd %XMM0, %XMM1
        movsd %XMM1, QWORD PTR [%ESP + 40]
        addsd %XMM1, %XMM0
3)      movsd QWORD PTR [%ESP + 48], %XMM1
        movsd QWORD PTR [%ESP + 4], %XMM0

In this case, instruction #2 was removed because of the value made
available by #1, and inst #1 was later deleted because it is now
never used before the stack slot is redefined by #3.

This occurs here and there in a lot of code with high spilling, on PPC
most of the removed loads/stores are LSU-reject-causing loads, which is
nice.

On X86, things are much better (because it spills more), where we nuke
about 1% of the instructions from SMG2000 and several hundred from eon.

More improvements to come...

3603cd62ae Turn any_extend nodes into zero_extend nodes when it allows us to remove an 
and instruction.  This allows us to compile stuff like this:

bool %X(int %X) {
        %Y = add int %X, 14
        %Z = setne int %Y, 12345
        ret bool %Z
}

to this:

_X:
        cmpl $12331, 4(%esp)
        setne %al
        movzbl %al, %eax
        ret

instead of this:

_X:
        cmpl $12331, 4(%esp)
        setne %al
        movzbl %al, %eax
        andl $1, %eax
        ret

This occurs quite a bit with the X86 backend.  For example, 25 times in
lambda, 30 times in 177.mesa, 14 times in galgel,  70 times in fma3d,
25 times in vpr, several hundred times in gcc, ~45 times in crafty,
~60 times in parser, ~140 times in eon, 110 times in perlbmk, 55 on gap,
16 times on bzip2, 14 times on twolf, and 1-2 times in many other SPEC2K
programs.

b3ddfc42af add two dag combines: 
(C1-X) == C2 --> X == C1-C2
(X+C1) == C2 --> X == C2-C1

This allows us to compile this:

bool %X(int %X) {
        %Y = add int %X, 14
        %Z = setne int %Y, 12345
        ret bool %Z
}

into this:

_X:
        cmpl $12331, 4(%esp)
        setne %al
        movzbl %al, %eax
        andl $1, %eax
        ret

not this:

_X:
        movl $14, %eax
        addl 4(%esp), %eax
        cmpl $12345, %eax
        setne %al
        movzbl %al, %eax
        andl $1, %eax
        ret

Testcase here: Regression/CodeGen/X86/compare-add.ll

2223aea6ed Implement matching constraints. We can now say things like this: 
%C = call int asm "xyz $0, $1, $2, $3", "=r,r,r,0"(int %A, int %B, int 4)

and get:

xyz r2, r3, r4, r2

note that the r2's are pinned together.  Yaay for 2-address instructions.

int %test(int %A, int %B) {
  %C = call int asm "xyz $0, $1, $2", "=r,r,r"(int %A, int %B)
  ret int %C
}

we now emit:

_test:
        or r2, r3, r3
        or r3, r4, r4
        xyz r2, r2, r3  ;; look here

3c55c54a87 - Use xor to clear integer registers (set R, 0). 
- Added a new format for instructions where the source register is implied
  and it is same as the destination register. Used for pseudo instructions
  that clear the destination register.
