Nick Lewycky 02d5f77d26 Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces.
Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

Owen Anderson b5049bebb3 Do away with the strange use of BitVectors in SSI, and just use normal sets. This makes the code much more C++/LLVM-ish.

Owen Anderson a62bf10651 SSI needs to require DT and DF transitively, since it uses them outside of its runOnFunction.
Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.

Nick Lewycky dddf5dcdaf Correctly handle the case where a comparison is created in one BasicBlock and
used by a terminator in another.

Nick Lewycky cbfe9b195c Fix up PHI nodes correctly in the presence of unreachable BBs, part two. Also
delete a newed pointer, and improve readability a little bit.

Nick Lewycky dd0e74ceee SSI construction should just go ahead and ignore instructions in unreachable
blocks.

Nick Lewycky ab81d2f5e9 There's no need to consider PHI nodes in the same block as the instruction
we're inserting sigma/phi functions for. Patch by Andre Tavares.

Nick Lewycky eb373ad2af Add some statistics to SSI so we can see what it's up to.
Add an -ssi-everything pass which calls createSSI on everything in the function.

Nick Lewycky cb23509546 Add Static Single Information construction pass written by André Tavares!
Use it by requiring it through the pass manager, then calling its createSSI
method on the variables that you want in SSI form.
