f5e25f32c7 Fix PR2355: bug in ChangeCompareStride. When the loop termination compare is the only use of its iv stride, the stride can be eliminated by moving it to another stride. If the scale is negative, swap the predicate instead of using a inverse predicate.

7375fbcbf2 Fix a bug in LSR's dead-PHI cleanup. If a PHI has a def-use chain that 
leads into a cycle involving a different PHI, LSR got stuck running
around that cycle looking for the original PHI. To avoid this, keep
track of visited PHIs and stop searching if we see one more than once.
This fixes PR2570.

9b93dd1f1a Refine the change in r52258 for avoiding use-before-def conditions 
when changing the stride of a comparison so that it's slightly
more precise, by having it scan the instruction list to determine
if there is a use of the condition after the point where the
condition will be inserted.

eacb7020ec For PR950: 
Update the test suite to accommodate the change from signed integer types
to signless integer types. The changes were of only a few kinds:

1. Make sure llvm-upgrade is run on the source which does the bulk of the
   changes automatically.

2. Change things like "grep 'int'" to "grep 'i32'"

3. In several tests bitcasting caused the same name to be reused in the
   same type plane. These had to be manually fixed. The fix was (generally)
   to leave the bitcast and provide the instruction with a new name. This
   should not affect the semantics of the test. In a few cases, the
   bitcasts were known to be superfluous and irrelevant to the test case
   so they were removed.

4. One test case uses a bytecode file which needed to be updated to the
   latest bytecode format.
