[mlir][python] Fix ir.Value type to not break other types (#167930)

Change in https://github.com/llvm/llvm-project/pull/166148 caused breaks
for some other types.
Specifically this error was seen in a downstream project
```
 _ods_ir.OpOperandList[_ods_ir.IntegerType]:

TypeError: type 'iree.compiler._mlir_libs._mlir.ir.OpOperandList' is not subscriptable

```
This PR tries to make those changes not affect the other types

[sanitizer_common] Add darwin-specific MemoryRangeIsAvailable (#167797)

The fixes a TOCTOU bug in the code that initializes shadow memory in
ASAN:


https://github.com/llvm/llvm-project/blob/4b05581bae0e3432cfa514788418fb2fc2144904/compiler-rt/lib/asan/asan_shadow_setup.cpp#L66-L91

1. During initialization, we call `FindDynamicShadowStart` to search the
memory mapping for enough space to dynamically allocate shadow memory.
2. We call `MemoryRangeIsAvailable(shadow_start, kHighShadowEnd);`,
which goes into `MemoryMappingLayout`.
3. We actually map the shadow with `ReserveShadowMemoryRange`.

In step 2, `MemoryMappingLayout` makes various allocations using the
internal allocator. This can cause the allocator to map more memory! In
some cases, this can actually allocate memory that overlaps with the
shadow region returned by` FindDynamicShadowStart` in step 1. This is
not actually fatal, but it memory corruption; MAP_FIXED is allowed to

[CMake][unittests] Teach export_executable_symbols about ALIAS targets (#167932)

DynamicLibraryTests has a workaround for AIX that calls
export_executable_symbols after add_llvm_unittest, instead of just
passing the `EXPORT_SYMBOLS` switch. At this point, the
default_gtest(_main) libraries is added to the linked library set.
However, default_gtest(_main) are ALIAS libraries. This PR replaces the
ALIAS libraries with the ALIASED_TARGET before passing it to
extract_symbols.py.

Fixes failure of the clang-ppc64-aix buildbot after #164794.
