[SimplifyCFG] Rerun PHI deduplication after common code sinkinkg (PR51092)
`SinkCommonCodeFromPredecessors()` doesn't itself ensure that duplicate PHI nodes aren't created.
I suppose, we could teach it to do that on-the-fly (& account for the already-existing PHI nodes,
& adjust costmodel), the diff will be bigger than this.
The alternative is to schedule a new EarlyCSE pass invocation somewhere later in the pipeline.
Clearly, we don't have any EarlyCSE runs in module optimization passline, so this pattern isn't cleaned up...
That would perhaps better, but it will again have some compile time impact.

[runtimes] Serialize all Lit params instead of passing them to add_lit_testsuite
add_lit_testsuite() takes Lit parameters passed to it and adds them
to the parameters used globally when running all test suites. That
means that a target like `check-all`, which ends up calling Lit on
the whole monorepo, will see the test parameters for all the individual
project's test suites.
So, for example, it would see `--param std=c++03` (from libc++abi), and
`--param std=c++03` (from libc++), and `--param whatever` (from another
project being tested at the same time). While always unclean, that works
when the parameters all agree. However, if the parameters share the same
name but have different values, only one of those two values will be used
and it will be incredibly confusing to understand why one of the test
suites is being run with the incorrect parameter value.
For that reason, this commit moves away from using add_lit_testsuite()'s
PARAM functionality, and serializes the parameter values for the runtimes
in the generated config.py file instead, which is local to the specific
test suite.

[GlobalOpt] Fix a miscompile when evaluating struct initializers.
The bug was that evaluateBitcastFromPtr attempts a narrowing to a struct's 0th
element of a store that covers other elements. While this is okay on the load
side, applying it to stores causes us to miss the writes to the additionally
covered elements.

[libomptarget] Keep the Shadow Pointer Map up-to-date
D105812 introduced a regression where if a PTR_AND_OBJ entry was mapped on the device, then the OBJ was deallocated and then reallocated at a different address, the Shadow Pointer Map would still contain an entry for the PTR but pointing to the old address. This caused test `env/base_ptr_ref_count.c` to fail.

[tests] Stablize tests for possible change in deref semantics
This is conceptually part of
e75a2dfe. This file contains both tests whose results don't change (with the right attributes added), and tests which fundementally regress with the current proposal. Doing the update took some care, thus the seperate change.
Here's the
e75a2dfe context repeated:
There's a potential change in dereferenceability attribute semantics in the nearish future. See llvm-dev thread "RFC: Decomposing deref(N) into deref(N) + nofree" and D99100 for context.
This change simply adds appropriate attributes to tests to keep transform logic exercised under both old and new/proposed semantics. Note that for many of these cases, O3 would infer exactly these attributes on the test IR.
This change handles the idiomatic pattern of a dereferenceable object being passed to a call which can not free that memory. There's a couple other tests which need more one-off attention, they'll be handled in another change.

Global variables with strong definitions cannot be freed
With the current deref semantics, this is redundant - since we assume that anything which is dereferenceable (ever) can't be freed - but it becomes neccessary for the deref-at-point semantics.
Testing wise, this is covered by test/CodeGen/X86/hoist-invariant-load.ll when -use-dereferenceable-at-point-semantics is active. I didn't bother duplicating the command line since a) it's an in-development mode, and b) the change is pretty obvious.

[Verifier] Improve incompatible attribute type check
A couple of attributes had explicit checks for incompatibility

by the typeIncompatible() check. We can drop these after adding
SwiftError to typeIncompatible().
However, the previous implementation of the check prints out all
attributes that are incompatible with a given type, even though
those attributes aren't actually used. This has the annoying
result that the error message changes every time a new attribute
is added to the list. Improve this by explicitly finding which
attribute isn't compatible and printing just that.
