Here is an example of missing variables location https://godbolt.org/z/K48osb9dK.
We see that arguments x, y of function foo are not available in debugger, and
corresponding DBG_VALUE instructions have undefined register operand instead of
variables locaton after Aarch64PreLegalizerCombiner pass. The reason is that
registers where variables are located are removed as dead (with instruction
G_TRUNC). We can use salvageDebugInfo analogue for gMIR to preserve debug

Going forward, this means that attributes in MLIR will no longer have
types as a first-class concept. This patch lays the groundwork to
incrementally remove or refactor code that relies on generic attributes
being typed. The immediate impact will be on attributes that rely on
`Attribute` containing a type, such as `IntegerAttr`,
`DenseElementsAttr`, and `ml_program::ExternAttr`, which will now need
to define a type parameter on their storage classes. This will save
memory as all other attribute kinds will no longer contain a type.
Moreover, it will not be possible to generically query the type of an
attribute directly. This patch provides an attribute interface
`TypedAttr` that implements only one method, `getType`, which can be
used to generically query the types of attributes that implement the
interface. This interface can be used to retain the concept of a "typed
attribute". The ODS-generated accessor for a `type` parameter
automatically implements this method.
Next steps will be to refactor the assembly formats of certain operations
that rely on `parseAttribute(type)` and `printAttributeWithoutType` to
remove special handling of type elision until `type` can be removed from
the dialect parsing hook entirely; and incrementally remove uses of
`TypedAttr`.

[mlir][DCA] Fix visiting call ops when run at function scopes
When dead-code analysis is run at the scope of a function, call ops to
other functions at the same level were being marked as unreachable,
since the analysis optimistically assumes the call op to have no known
predecessors and that all predecessors are known, but the callee would
never get visited.
This patch fixes the bug by checking if a referenced function is above
the top-level op of the analysis, and is thus considered an external
callable.
