65e2da3b4d Fix handling of overflow in loop calculation by adding new UDiv SCEV. This SCEV
is disabled in the sense that it will refuse to create one from a UDiv
instruction, until the code is better tested.

d6dac0eebc Let scalar-evolution analyze loops with an unsigned comparison for the exit
condition. Fixes 1597.

06323bfe03 Don't assume it's safe to transform a loop just because it's dominated by any
comparison. Fixes bug 1598.

eefdebe002 Handle decrementing loops properly. Fixes PR1533.
Always pass the constant as the second parameter to HowManyLessThans.

Remove obsolete "isSigned" parameter.

0f5aed5648 Make the llvm-runtest function much more amenable by eliminating all the
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.

908504347b For PR411:
Update these tests to not use the same name even though the type of the
value differs. After PR411 hits, type planes will be gone and it will be
illegal for a name to be used twice, regardless of type.

e3ff5ada8a For PR761:
Remove "target endian/pointersize" or add "target datalayout" to make
the test parse properly or set the datalayout because defaults changes.

For PR645:
Make global names use the @ prefix.

For llvm-upgrade changes:
Fix test cases or completely remove use of llvm-upgrade for test cases
that cannot survive the new renaming or upgrade capabilities.
