e4a97f4bee If a global is just loaded and restored, realize that it is not changing 
value.  This allows us to turn more globals into constants and eliminate them.
This patch implements GlobalOpt/load-store-global.llx.

Note that this patch speeds up 255.vortex from:

Output/255.vortex.out-cbe.time:program 7.640000
Output/255.vortex.out-llc.time:program 9.810000

to:

Output/255.vortex.out-cbe.time:program 7.250000
Output/255.vortex.out-llc.time:program 9.490000

Which isn't bad at all!

3d61b688a9 This optimization makes MANY phi nodes that all have the same incoming value. 
If this happens, detect it early instead of relying on instcombine to notice
it later.  This can be a big speedup, because PHI nodes can have many
incoming values.

fdd41995d8 Transform this: 
%X = alloca ...
  %Y = alloca ...
    X == Y

into false.  This allows us to simplify some stuff in eon (and probably
many other C++ programs) where operator= was checking for self assignment.
Folding this allows us to SROA several additional structs.

1cde11aa95 shld is a very high latency operation. Instead of emitting it for shifts of 
two or three, open code the equivalent operation which is faster on athlon
and P4 (by a substantial margin).

For example, instead of compiling this:

long long X2(long long Y) { return Y << 2; }

to:

X3_2:
        movl 4(%esp), %eax
        movl 8(%esp), %edx
        shldl $2, %eax, %edx
        shll $2, %eax
        ret

Compile it to:

X2:
        movl 4(%esp), %eax
        movl 8(%esp), %ecx
        movl %eax, %edx
        shrl $30, %edx
        leal (%edx,%ecx,4), %edx
        shll $2, %eax
        ret

Likewise, for << 3, compile to:

X3:
        movl 4(%esp), %eax
        movl 8(%esp), %ecx
        movl %eax, %edx
        shrl $29, %edx
        leal (%edx,%ecx,8), %edx
        shll $3, %eax
        ret

This matches icc, except that icc open codes the shifts as adds on the P4.

        movl 8(%esp), %edx

        adcl %edx, %edx
        ret
X:
        movl 4(%esp), %eax
        addl %eax, %eax

instead of:

        movl 8(%esp), %edx
        shldl $1, %eax, %edx

70e351fb1c Simplify handling of shifts to be the same as we do for adds. Add support 
for (X * C1) + (X * C2) (where * can be mul or shl), allowing us to fold:

   Y+Y+Y+Y+Y+Y+Y+Y

into
         %tmp.8 = shl long %Y, ubyte 3           ; <long> [#uses=1]

instead of

        %tmp.4 = shl long %Y, ubyte 2           ; <long> [#uses=1]
        %tmp.12 = shl long %Y, ubyte 2          ; <long> [#uses=1]
        %tmp.8 = add long %tmp.4, %tmp.12               ; <long> [#uses=1]

This implements add.ll:test25

Also add support for (X*C1)-(X*C2) -> X*(C1-C2), implementing sub.ll:test18

7a8d26a581 Fold: 
(X + (X << C2)) --> X * ((1 << C2) + 1)
   ((X << C2) + X) --> X * ((1 << C2) + 1)

This means that we now canonicalize "Y+Y+Y" into:

        %tmp.2 = mul long %Y, 3         ; <long> [#uses=1]

instead of:

        %tmp.10 = shl long %Y, ubyte 1          ; <long> [#uses=1]
        %tmp.6 = add long %Y, %tmp.10               ; <long> [#uses=1]

d9387fee02 Tune compression: 
bzip2: block size 9 -> 5, reduces memory by 400Kbytes, doesn't affect speed
       or compression ratio on all but the largest bytecode files (>1MB)
zip:   level 9 -> 6, this speeds up compression time by ~30% but only
       degrades the compressed size by a few bytes per megabyte. Those few
       bytes aren't worth the effort.

3083f2a424 Do not compute the predecessor list for a block unless we need it. 
This speeds up simplifycfg on this program, from 44.87s to 0.29s (with
a profiled build):

 #define CL0(a) case a: goto c;
 #define CL1(a) CL0(a##0) CL0(a##1) CL0(a##2) CL0(a##3) CL0(a##4) CL0(a##5) \

 void f();

 void a() {
     int b;
  c: switch (b) {
         CL4(1)
     }
 }

This testcase is contrived to expose N^2 behavior, but this patch should speedup
simplifycfg on any programs that use large switch statements.  This testcase
comes from GCC PR17895.

4b741eab69 Fix three bugs: 
1. Calls to external global VARIABLES should not be treated as a call to an
    external function
 2. Efficiently deleting an element from a vector by using std::swap with
    the back, then pop_back is NOT a good way to keep the vector sorted.
 3. Our hope of having stuff get deleted by making them redundant just won't
    work.  In particular, if we have three calls in sequence that should be
    merged: A, B, C   first we unify B into A.  To be sure that they appeared
    identical (so B would be erased) we set B = A.  On the next step, we
    unified C into A and set C = A.  Unfortunately, this is no guarantee that
    C = B, so we would fail to delete the dead call.  Switch to a more
    explicit scheme.
