Revert a portion of Dan's change r71018 that I'm convinced is wrong.
Dan was trying to catch the case where a basic block ends with a conditional
branch to the fall-through block.  In this case, all the instructions have
been moved out of FromBBI, leaving it empty.  It cannot end with a
conditional branch.  As the existing comment indicates, it will always fall
through to the next block.  If the block already had the next block (NBB)
listed as a successor, the preceding loop has a check for that and does not
remove it.  Thus, we need to check and add the successor only when it is
not already listed.

With Dan's change, the empty block often ends up with the fall-through
successor listed twice.  This exposed the problem in pr4195, where
CodePlacementOpt did not handle the same predecessor listed more than once.
It is also at least partially responsible for pr4202 and probably a similar
issue with Thumb branches being out of range.

Fix for PR4121. If TwoAddressInstructionPass removes a dead def, and the regB
operand was killed, the kill needs to be removed from regB's VarInfo.

Add three new helper routines, getNoopOrZeroExtend,
getNoopOrSignExtend, and getTruncateOrNoop. These are similar
to getTruncateOrZeroExtend etc., except that they assert that
the conversion is either not widening or narrowing, as
appropriate. These will be used in some upcoming fixes.

Add an int64_t variant of abs, for host environments
without one.  Use it where we were using abs on
int64_t objects.
(I strongly suspect the casts to unsigned in the
fragments in LoopStrengthReduce are not doing whatever
the original intent was, but the obvious change to
uint64_t doesn't work.  Maybe later.)

Add support for GCC compatible builtin setjmp and longjmp intrinsics. This is
a supporting preliminary patch for GCC-compatible SjLJ exception handling. Note that these intrinsics are not designed to be invoked directly by the user, but
rather used by the front-end as target hooks for exception handling.
