Nick Desaulniers e1bae23f6f [SCCP] do not clean up dead blocks that have their address taken 
[SCCP] do not clean up dead blocks that have their address taken

Fixes a crash observed in IPSCCP.

Because the SCCPSolver has already internalized BlockAddresses as
Constants or ConstantExprs, we don't want to try to update their Values
in the ValueLatticeElement. Instead, continue to propagate these
BlockAddress Constants, continue converting BasicBlocks to unreachable,
but don't delete the "dead" BasicBlocks which happen to have their
address taken.  Leave replacing the BlockAddresses to another pass.
