Arthur Eubanks 4a10029d7e [NewPM][Attributor] Pin tests with -attributor to legacy PM
All these tests already explicitly test against both legacy PM and NPM.

$ sed -i 's/ -attributor / -attributor -enable-new-pm=0 /g' $(rg --path-separator // -l -- -passes=)
$ sed -i 's/ -attributor-cgscc / -attributor-cgscc -enable-new-pm=0 /g' $(rg --path-separator // -l -- -passes=)

Now all tests in Transforms/Attributor/ pass under NPM.

All tests are updated, except wrapper.ll since it is not working nicely
with newly created functions.

Johannes Doerfert e2b53a4c05 [Attributor][NFC] Remove obsolete option from tests
Since D76871 it is sufficient to run `opt -atributor` or
`-attributor-cgscc`.

Johannes Doerfert 3ca54f4595 [Attributor] Unify testing (=updates,prefixes,run configurations,...)
When the Attributor was created the test update scripts were not well
suited to deal with the challenges of IR attribute checking. This
partially improved.

Since then we also added three additional configurations that need
testing; in total we now have the following four:
{ TUNIT, CGSCC } x { old pass manager (OPM), new pass manager (NPM) }

Finally, the number of developers and tests grew rapidly (partially due
to the addition of ArgumentPromotion and IPConstantProp tests), which
resulted in tests only being run in some configurations, different
prefixes being used, and different "styles" of checks being used.

Due to the above reasons I believed we needed to take another look at
the test update scripts. While we started to use them, via UTC_ARGS:
--enable/disable, the other problems remained. To improve the testing
situation for *all* configurations, to simplify future updates to the
test, and to help identify subtle effects of future changes, we now use
the test update scripts for (almost) all Attributor tests.

An exhaustive prefix list minimizes the number of check lines and makes
it easy to identify and compare configurations.

Tests have been adjusted in the process but we tried to keep their
intend unchanged.

Johannes Doerfert 282f5d7ad1 [Attributor] Derive memory location attributes (argmemonly, ...)
In addition to memory behavior attributes (readonly/writeonly) we now
derive memory location attributes (argmemonly/inaccessiblememonly/...).
The former is part of AAMemoryBehavior and the latter part of
AAMemoryLocation. While they are similar in nature it got messy when
they were put in a single AA. Location attributes for arguments and
floating values will follow later.

Note that both memory attributes kinds can derive readnone. If there are
no accesses AAMemoryBehavior will derive readnone. If there are accesses
but only to stack (=local) locations AAMemoryLocation will derive
readnone.

Johannes Doerfert 23f41f16d4 [Attributor] Use fine-grained liveness in all helpers
We used coarse-grained liveness before, thus we looked if the
instruction was executed, but we did not use fine-grained liveness,
hence if the instruction was needed or could be deleted even if the
surrounding ones are live. This patches introduces this level of
liveness checks together with other liveness queries, e.g., for uses.

For more control we enforce that all liveness queries go through the
Attributor.

Test have been adjusted to reflect the changes or augmented to prevent
deletion of the parts we want to check.

Johannes Doerfert 412a0101a9 [Attributor][FIX] Do not derive nonnull and dereferenceable w/o access
An inbounds GEP results in poison if the value is not "inbounds", not in
UB. We accidentally derived nonnull and dereferenceable from these
inbounds GEPs even in the absence of accesses that would make the poison
to UB.

Hideto Ueno 96552036e3 [Attributor] Copy or port test cases related to Attributor to` Attributor` test folder
Summary:
This patch moves the test cases related to Attributor to `Transforms/Attributor` folder.
We have used `Transforms/FunctionAttrs` as the primary folder for Attributor test but we need to change testing way now.

For the test cases which I think functionattrs doesn't infer anything something like (willreturn, nosync, value-simplify, h2s ..etc), I moved them with the command `git mv`.

For the test cases in which functoinattrs and attributor are tested, I copied the test to the folder and remove the check only used by functoinattrs.
