This revision replaces the LLVM dialect NullOp by the recently
introduced ZeroOp. The ZeroOp is more generic in the sense that it
represents zero values of any LLVM type rather than null pointers only.
This is a follow to https://github.com/llvm/llvm-project/pull/65508
IR is now always parsed in opaque pointer mode, unless
-opaque-pointers=0 is explicitly given. There is no automatic
detection of typed pointers anymore.
The -opaque-pointers=0 option is added to any remaining IR tests
that haven't been migrated yet.

Instead of importing constant expressions recursively, the revision
walks all dependencies of an LLVM constant iteratively. The actual
conversion then iterates over a list of constants and all intermediate
constant values are added to the value mapping. As a result, an LLVM IR
constant maps to exactly one MLIR operation per function. The revision
adapts the existing tests since the constant ordering changed for
aggregate types. Additionally, it adds extra tests that mix aggregate
constants and constant expressions.
Depends on D137416

Insert constants and globals in order by maintaining the position
of the constant and global inserted last. Update the tests
to reflect the updated insertion order. Also make sure functions
are always inserted at the end of the module instead of at
the second last position and delete a spurious function in
the intrinsic.ll that seems to exist to avoid the first
function under test ends up at the end of the module.

Default attributes were only handled by ODS accessors generated with the
intention that these behave as if set attributes. This addresses the
long standing TODO to address this inconsistency. Moving the
initialization to construction vs every access. Removing need for
duplicated default attribute population in python bindings.
Switch some of the OpenMP ones to optional attribute with default as the
currently set default values are not legal. May need to dig more there.
Switched LinAlg generated ones to optional attribute with default as its
quite widely used and unclear where it falls on two different
interpretations.

This patch "modernizes" the LLVM `insertvalue` and `extractvalue`
operations to use DenseI64ArrayAttr, since they only require an array of
indices and previously there was confusion about whether to use i32 or
i64 arrays, and to use assembly format.

And move importer test files from `test/Target/LLVMIR` into
`test/Target/LLVMIR/Import`.
We simply translate struct-type ConstantAggregate(Zero) into a
serious of `llvm.insertvalue` operations against a `llvm.undef` root.
Note that this doesn't affect the original logics on translating
vector/array-type ConstantAggregate values.
