When only a single value has been seen, new PHIDefs are never needed.

We need to wait until we meet a PHIDef in its defining block before resurrecting
PHIKills in the predecessors.

This should unbreak the llvm-gcc-build-x86_64-darwin10-x-mingw32-x-armeabi bot.

Fix bug where bitwise-AND was being used and it should have been bitwise-OR.

Add code to emulate ADD (immediate, Thumb) Arm instruction.

Add addition context to EmulateInstruction contexts.

David Greene changed CannotYetSelect() to print the full DAG including multiple
copies of operands reached through different paths in the DAG.  Unfortunately
this blows up exponentially in some cases.  The depth limit of 100 is way too
high to prevent this -- I'm seeing a message string of 150MB with a depth of
only 40 in one particularly bad case, even though the DAG has less than 200
nodes.  Part of the problem is that the printing code is following chain
operands, so if you fail to select an operation with a chain, the printer will
follow all the chained operations back to the entry node.

Values that map to a single new value in a new interval after splitting don't
need new PHIDefs, and if the parent value was never rematerialized the live
range will be the same.

    uint32_t

Also did a little cleanup on the ProcessGDBRemote stdio file handle
code.

Introduce CFGImplicitDtor::isNoReturn() to query whether a destructor actually returns.  Use this for -Wreturn-type to prune false positives reported in PR 6884.
