really does need to be a vector type, because
TargetLowering::getOperationAction for SIGN_EXTEND_INREG uses that type,
and it needs to be able to distinguish between vectors and scalars.

Also, fix some more issues with legalization of vector casts.

Dan pointed out checking whether a node is dead by comparing its opcode to ISD::DELETED_NODE is not safe. Use a DAGUpdateListener to remove dead nodes from work list instead.

Fix a critical bug in 64-bit atomic operation lowering for 32-bit. The results of the cmpxchg8b instructions are being thrown away when it branches back to the top of the checking loop. This means the loop always compares against the old value and this can result in a dead lock.

when the default case is winnowed down to be infeasible.  When all
cases were ruled out (and the analysis state for the default case
would be infeasible) we would still consider the default case
possible.  This fixes PR 5969.

putting relocations into the constant pool - this isn't needed
for correctness and in the rare occasion it happens would pull
us out of fast isel for the block.

If fast-isel application startup time ever becomes an issue we
can add better support for these addresses instead of bailing.

not just the viable ones.  This is reasonable because the most common use of
deleted functions is to exclude some implicit conversion during calls;  users
therefore will want to figure out why some other options were excluded.

Started sorting overload results.  Right now it just sorts by location in the
translation unit (after putting viable functions first), but we can do better than
that.

Changed bool OnlyViable parameter to PrintOverloadCandidates to an enum for better
self-documentation.

suggestions follow recovery. Additionally, add a note to these
diagnostics which suggests a fix-it for changing the behavior to what
the user probably meant. Examples:

  if (i & j == k) {
        ^~~~~~~~

t.cpp:2:9: note: place parentheses around the & expression to evaluate it first
  if (i & j == k) {
