this reduces the time for -simplifycfg in a debug build from 106s to 14.82s

9b5b1905db Fix a bugpoint crash that JeffC noticed, looking like this: 
*** Attempting to perform final cleanups: Final cleanups failed.  Sorry. :(  Ple
ase report a bug!

<llc>llc.exe: bytecode didn't read correctly.
llc.exe: bytecode didn't read correctly.
<crash>
Assertion failed: M && "You can't write a null module!!", file c:\llvm\lib\bytec
ode\writer\writer.cpp, line 1094


The fact that llc bombed (in this case) is ok, but bugpoint shouldn't crash after this.

84734ce8ef Fix a bug in the 'store fpimm, ptr' -> 'store intimm, ptr' handling code. 
Changing 'op' here caused us to not enter the store into a map, causing
reemission of the code!!  In practice, a simple loop like this:

no_exit:                ; preds = %no_exit, %entry
        %indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ]            ; <uint> [#uses=3]
        %tmp.4 = getelementptr "complex long double"* %P, uint %indvar, uint 0          ; <double*> [#uses=1]
        store double 0.000000e+00, double* %tmp.4
        %indvar.next = add uint %indvar, 1              ; <uint> [#uses=2]
        %exitcond = seteq uint %indvar.next, %N         ; <bool> [#uses=1]
        br bool %exitcond, label %return, label %no_exit

was being code gen'd to:

.LBBtest_1:     # no_exit
        movl %edx, %esi
        shll $4, %esi
        movl $0, 4(%eax,%esi)
        movl $0, (%eax,%esi)
        incl %edx
        movl $0, (%eax,%esi)
        movl $0, 4(%eax,%esi)
        cmpl %ecx, %edx
        jne .LBBtest_1  # no_exit

Note that we are doing 4 32-bit stores instead of 2.  Now we generate:

.LBBtest_1:     # no_exit
        movl %edx, %esi
        incl %esi
        shll $4, %edx
        movl $0, (%eax,%edx)
        movl $0, 4(%eax,%edx)
        cmpl %ecx, %esi
        movl %esi, %edx
        jne .LBBtest_1  # no_exit

This is much happier, though it would be even better if the increment of ESI
was scheduled after the compare :-/

8e0de32cc9 Adjust this test to pass after recent CFE changes. We now generate: 
%XX = global int cast (int* getelementptr ([2 x int]* getelementptr (%struct.S* null, int 0, uint 0), int 0, int 1) to int)

which is the literal translation of the testcase :)
