eba1b74df3 implement a simple fneg optimization/propagation thing. This compiles: 
CodeGen/PowerPC/fneg.ll into:

_t4:
        fmul f0, f3, f4
        fmadd f1, f1, f2, f0
        blr

instead of:

_t4:
        fneg f0, f3
        fmul f0, f0, f4
        fmsub f1, f1, f2, f0
        blr

e9e48bcf28 Fix for PR1406: 
v1 =
r2 = move v1
   = op r2<kill>
...
r2 = move v1
   = op r2<kill>

Clear the first r2 kill if v1 and r2 are joined.

afe2314bb0 Give names to the final result values of the part_set computations. This 
just aids in readability and debugability of the output. No functional change.

03903c3181 The wrapping behavior of part_set is not desirable. Adjust the 
documentation to describe the desired behavior.

0f0310012d Revise definition of part_select. The wrapping behavior is not useful so 
in the reverse case the only difference is that the bits are returned in
reverse order.

f704d8f166 Add passes -view-cfg and -view-cfg-only that are like -print-cfg and 
-print-cfg-only except they use the ViewCFG function, which displays the
CFG rendered with graphviz with gv.

17cd3485e1 Use templates for the GraphType for DefaultDOTGraphTraits' members instead 
of just using void*. This allows it to be used with graph adapters like
Inverse.

a17d02ad08 Add some things needed by the llvm-gcc version supporting bit accurate integer 
types:
1. Functions to compute div/rem at the same time.
2. Further assurance that an APInt with 0 bitwidth cannot be constructed.
3. Left and right rotate operations.
4. An exactLogBase2 function which requires an exact power of two or it
   returns -1.

100919126f Emit multiple common EH frames for multiple (including blank) personality 
functions. This partly fixes PR1414: now we're restricted only to one
personality function per eh frame, not per module. Further work on
"multiple personalities" topic needs representative example.
