If some symbols are marked with dllexport, we still want to export
all symbols if -export-all-symbols is specified. Previously, this
only worked as it should for DLL output, not for EXE.

[clang-tidy] performance-unnecessary-copy-initialization: Create option to exclude container types from triggering the check.

Add string list option of type names analagous to `AllowedTypes` which lets
users specify a list of ExcludedContainerTypes.

Types matching this list will not trigger the check when an expensive variable
is copy initialized from a const accessor method they provide, i.e.:

```
ExcludedContainerTypes = 'ExcludedType'

void foo() {
  ExcludedType<ExpensiveToCopy> Container;
  const ExpensiveToCopy NecessaryCopy = Container.get();
}
```

Even though an expensive to copy variable is copy initialized the check does not
trigger because the container type is excluded.

This is useful for container types that don't own their data, such as view types
where modification of the returned references in other places cannot be reliably
tracked, or const incorrect types.

Reland of 31859f89.

This change implements new DAG notes GLOBAL_GET/GLOBAL_SET, and
lowering methods for load and stores of reference types from IR
globals. Once the lowering creates the new nodes, tablegen pattern
matches those and converts them to Wasm global.get/set.

[clang-tidy] performance-unnecessary-copy-initialization: Disable check when variable and initializer have different replaced template param types.

This can happen when a template with two parameter types is instantiated with a

others that rely on an implicit type conversion.

The test cases illustrate when the check should trigger and when not.

Update shl/lshr/ashr costs based on the worst case costs from the script in D103695 - many of the 128-bit shifts (usually where integer multiplies aren't used) have similar behaviour to AVX1 so we can merge them.

We'd lost AVX1 test coverage due to bulldozer (XOP) trying to use the same check prefixes - we really need to fix the update script to avoid this!

AMDGPU can assume Elf64 so doesn't need to abstract over Elf32

We should only add the fake lowering entry for the matrix remark if the
transpose is not lowered on its own.  `MapVector::insert` is used to insert
the entry during proper lowering which does not overwrite the fake entry in
the map.

We actually had test coverage for this but the reference output code was
wrong; it was storing undef rather than the transposed column.

Also add an assert that would have caught this.
