[SCCP] Simplify CFG in SCCP as well
Currently, we only remove dead blocks and non-feasible edges in
IPSCCP, but not in SCCP. I'm not aware of any strong reason for
that difference, so this patch updates SCCP to perform the CFG
cleanup as well.
Compile-time impact seems to be pretty minimal, in the 0.05%
geomean range on CTMark.
For the test case from https://reviews.llvm.org/D126962#3611579
the result after -sccp now looks like this:
define void @test(i1 %c) {
entry:
br i1 %c, label %unreachable, label %next
next:
unreachable
unreachable:
call void @bar()
unreachable
}
-jump-threading does nothing on this, but -simplifycfg will produce
the optimal result.

[CompileTime] [Passes] Avoid computing unnecessary analyses. NFC
Similar to c515b2f39e77, If there are no loops in the function as seen
through LI, we should avoid computing the remaining expensive analyses
(such as SCEV, BPI). Reordered the analyses requests and early return
if there are no loops.
The logic of avoiding expensive analyses is applied to LoopVectorizer,
LoopLoadElimination and LoopUnrollPass, i.e. all function passes which operate
on loops.
This is an NFC with compile time improvement.

[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.

[NewPM] Hide pass manager debug logging behind -debug-pass-manager-verbose
Printing pass manager invocations is fairly verbose and not super
useful.
This allows us to remove DebugLogging from pass managers and PassBuilder
since all logging (aside from analysis managers) goes through
instrumentation now.
This has the downside of never being able to print the top level pass
manager via instrumentation, but that seems like a minor downside.

-debug-pass is a legacy PM only option.
Some tests checks that the pass returned that it made a change,

Some tests check that passes are freed at the proper time, which is also
not relevant to the NPM.

[BasicAA] Use PhiValuesAnalysis if available when handling phi alias
By using PhiValuesAnalysis we can get all the values reachable from a phi, so
we can be more precise instead of giving up when a phi has phi operands. We
can't make BaseicAA directly use PhiValuesAnalysis though, as the user of
BasicAA may modify the function in ways that PhiValuesAnalysis can't cope with.
For this optional usage to work correctly BasicAAWrapperPass now needs to be not
marked as CFG-only (i.e. it is now invalidated even when CFG is preserved) due
to how the legacy pass manager handles dependent passes being invalidated,
namely the depending pass still has a pointer to the now-dead dependent pass.
