A previous commit (f2b94bd) added some unnecessary statements that
dereferenced operations only to get the operations back. This patch
removes the unnecessary statements.

The visitor functions for `Region` and `Block` types did not always
check the value returned by recursive calls. This caused the top-level
visitor invocation to return `WalkResult::advance()` even if one or more
recursive invocations returned `WalkResult::interrupt()`. This patch
fixes the problem by check if any recursive call is interrupted, and if
so, return `WalkResult::interrupt()`.

This commit restructures how TypeID is implemented to ideally avoid
the current problems related to shared libraries. This is done by changing
the "implicit" fallback path to use the name of the type, instead of using
a static template variable (which breaks shared libraries). The major downside to this
is that it adds some additional initialization costs for the implicit path. Given the
use of type names for uniqueness in the fallback, we also no longer allow types
defined in anonymous namespaces to have an implicit TypeID. To simplify defining
an ID for these classes, a new `MLIR_DEFINE_EXPLICIT_INTERNAL_INLINE_TYPE_ID` macro
was added to allow for explicitly defining a TypeID directly on an internal class.
To help identify when types are using the fallback, `-debug-only=typeid` can be
used to log which types are using implicit ids.
This change generally only requires changes to the test passes, which are all defined
in anonymous namespaces, and thus can't use the fallback any longer.

- Generic visitors invoke operation callbacks before/in-between/after visiting the regions
attached to an operation and use a `WalkStage` to indicate which regions have been
visited.
- This can be useful for cases where we need to visit the operation in between visiting
regions attached to the operation.
