This just adds the simulator platforms to the lldbplatform enumerations
and the respective test decorator.
The platform names for the simulator are just the SDK names since D85537, so
that's why we are not using LLDB's usual platform names here (e.g., SDK =
"iphonesimulator" vs LLDB platform ="ios-simulator").
Also removes the duplicate platform enumaration in lldbplatformutil.py.

TestDialect has many operations and they all live in ::mlir namespace.
Sometimes it is not clear whether the ops used in the code for the test passes
belong to Standard or to Test dialects.
Also, with this change it is easier to understand what test passes registered
in mlir-opt are actually passes in mlir/test.

This originally broke the TestQuoting which explicitly called buildDefault
instead of calling build() and marking the test as no_debug_info_test.
TestQuoting has been rewritten by now and is using `build`, so this should now
pass on all platforms.
Original summary:
The Darwin builder currently assumes in `getArchCFlags` that the passed `arch`
value is an actual string it can string.join with vendor/os/version/env strings:
```
triple = '-'.join([arch, vendor, os, version, env])
```
However this is not true for most tests as we just pass down the `arch=None`
default value from `TestBase.build`. This causes that if we actually end up in
this function we just error out when concatenating `None` with the other actual
strings of vendor/os/version/env. What we should do instead is check that if
there is no test-specific architecture that we fall back to the configuration's
architecture value.
It seems we already worked around this in `builder.getArchSpec` by explicitly
falling back to the architecture specified in the configuration.
This patch just moves this fallback logic to the top `build` function so that it
affects all functions called from `TestBase.build`.

`fork` is marked as `__WATCHOS_PROHIBITED __TVOS_PROHIBITED` so the test source

This is a follow up to D88792 which found an issue in a call to PExpectTest's
expect function that allows passing a string to the `substrs` parameter. However
this issue was found by just grepping and TestPExpect's expect function is still
accepting a single string as a value to `substrs`.
This patch adds the same sanity check that D88792 added to the PExpectTest's
implementation of `expect` and also adds a small test for it.

When replacing an assume(false) with a store, we have to be more careful
with the order we insert the new access. This patch updates the code to
look at the accesses in the block to find a suitable insertion point.
Alterantively we could check the defining access of the assume, but IIRC
there has been some discussion about making assume() readnone, so
looking at the access list might be more future proof.
Fixes PR48072.

To accommodate frame layouts that have both fixed and scalable objects
on the stack, describing a stack location or offset using a pointer + uint64_t
is not sufficient. For this reason, we've introduced the StackOffset class,
which models both the fixed- and scalable sized offsets.
The TargetFrameLowering::getFrameIndexReference is made to return a StackOffset,
so that this can be used in other interfaces, such as to eliminate frame indices
in PEI or to emit Debug locations for variables on the stack.
This patch is purely mechanical and doesn't change the behaviour of how
the result of this function is used for fixed-sized offsets. The patch adds
various checks to assert that the offset has no scalable component, as frame
offsets with a scalable component are not yet supported in various places.

Rationale:
Children of a syntax tree had forward links only, because there was no
need for reverse links.
This need appeared when we started mutating the syntax tree.
On a forward list, to remove a target node in O(1) we need a pointer to the node before the target. If we don't have this "before" pointer, we have to find it, and that requires O(n).
So in order to remove a syntax node from a tree, we would similarly need to find the node before to then remove. This is both not ergonomic nor does it have a good complexity.

The LinalgDependenceGraph and alias analysis provide the necessary analysis for the Linalg fusion on buffers case.
However this is not enough for linalg on tensors which require proper memory effects to play nicely with DCE and other transformations.
This revision adds side effects to Linalg ops that were previously missing and has 2 consequences:
1. one example in the copy removal pass now fails since the linalg.generic op has side effects and the pass does not perform alias analysis / distinguish between reads and writes.
2. a few examples in fusion-tensor.mlir need to return the resulting tensor otherwise DCE automatically kicks in as part of greedy pattern application.

Some targets may add required passes via
TargetMachine::registerPassBuilderCallbacks(). We need to run those even
under -O0. As an example, BPFTargetMachine adds
BPFAbstractMemberAccessPass, a required pass.
This also allows us to clean up BackendUtil.cpp (and out-of-tree Rust
usage of the NPM) by allowing us to share added passes like coroutines
and sanitizers between -O0 and other optimization levels.
Tests are a continuation of those added in
https://reviews.llvm.org/D89083.
In order to prevent TargetMachines from adding unnecessary optimization
passes at -O0, TargetMachine::registerPassBuilderCallbacks() will be
changed to take an OptimizationLevel, but that will be done separately.

The previous behavior was fragile when building an OpPassManager using a
string, as it was forcing the client to ensure the string to outlive the
entire PassManager.
This isn't a performance sensitive area either that would justify
optimizing further.
Summary:
Object of type `Compilation` now can keep a callback that is called
after each execution of `Command`. This must simplify adaptation of
clang in custom distributions and allow facilities like collection of
execution statistics.
