Chandler Carruth 14ee003f1a [SDAG] Fix a case where we would iteratively legalize a node during 
combining by replacing it with something else but not re-process the
node afterward to remove it.

In a truly remarkable stroke of bad luck, this would (in the test case
attached) end up getting some other node combined into it without ever
getting re-processed. By adding it back on to the worklist, in addition
to deleting the dead nodes more quickly we also ensure that if it
*stops* being dead for any reason it makes it back through the
legalizer. Without this, the test case will end up failing during
instruction selection due to an and node with a type we don't have an
instruction pattern for.

It took many million runs of the shuffle fuzz tester to find this.
