[test] Use -passes syntax when specifying pipeline in some more tests
The legacy PM is deprecated, so update a bunch of lit tests running
opt to use the new PM syntax when specifying the pipeline.
In this patch focus has been put on test cases for ConstantMerge,
ConstraintElimination, CorrelatedValuePropagation, GlobalDCE,
GlobalOpt, SCCP, TailCallElim and PredicateInfo.

Recommit "[SCCP] Remove forcedconstant, go to overdefined instead"
This includes a fix for cases where things get marked as overdefined in
ResolvedUndefsIn, but we later discover a constant. To avoid crashing,
we consistently bail out on overdefined values in the visitors. This is
similar to the previous behavior with forcedconstant.
This reverts the revert commit 02b72f564c8be0b4f4337d5c4a3fcf7e8018a818.

Recommit "[SCCP] Remove forcedconstant, go to overdefined instead"
This version includes a fix for a set of crashes caused by marking
values depending on a yet unknown & tracked call as overdefined.
Recommit "[SCCP] Remove forcedconstant, go to overdefined instead"
This version includes a fix for a set of crashes caused by marking
values depending on a yet unknown & tracked call as overdefined.
In some cases, we would later discover that the call has a constant
result and try to mark a user of it as constant, although it was already
marked as overdefined. Most instruction handlers bail out early if the
instruction is already overdefined. But that is not necessary for
CastInsts for example. By skipping values that depend on skipped
calls, we resolve the crashes and also improve the precision in some
cases (see resolvedundefsin-tracked-fn.ll).
Note that we may not skip PHI nodes that may depend on a skipped call,
but they can be safely marked as overdefined, as we bail out early if
the PHI node is overdefined.
This reverts the revert commit
a74b31a3e9cd844c7ce2087978568e3f5ec8519.

[SCCP] Remove forcedconstant, go to overdefined instead
This patch removes forcedconstant to simplify things for the
move to ValueLattice, which includes constant ranges, but no
forced constants.
This patch removes forcedconstant and changes ResolvedUndefsIn
to mark instructions with unknown operands as overdefined. This
means we do not do simplifications based on undef directly in SCCP
any longer, but this seems to hardly come up in practice (see stats
below), presumably because InstCombine & others take care
of most of the relevant folds already.
It is still beneficial to keep ResolvedUndefIn, as it allows us delaying
going to overdefined until we propagated all known information.
I also built MultiSource, SPEC2000 and SPEC2006 and compared
sccp.IPNumInstRemoved and sccp.NumInstRemoved. It looks like the impact
is quite low:

[SCCP] Add a test for switches on undef.
Without this test, you can just remove the code fixing the
switch to the first constant in ResolvedUndefs in and everything

is removed. Found while refactoring SCCP to integrate undef in
the solver.
