[NFC] Rename `Intrinsic::getDeclaration` to `getOrInsertDeclaration` (#111752)

Rename the function to reflect its correct behavior and to be consistent
with `Module::getOrInsertFunction`. This is also in preparation of
adding a new `Intrinsic::getDeclaration` that will have behavior similar
to `Module::getFunction` (i.e, just lookup, no creation).

[NFC][RemoveDIs] Use iterators for insertion at various call-sites (#84736)

These are the last remaining "trivial" changes to passes that use
Instruction pointers for insertion. All of this should be NFC, it's just
changing the spelling of how we identify a position.

In one or two locations, I'm also switching uses of getNextNode etc to
using std::next with iterators. This too should be NFC.

[llvm] Remove SmallSet from MachineInstr.h

[llvm] Remove SmallSet from MachineInstr.h

`MachineInstr.h` is a commonly included file and this includes
`llvm/ADT/SmallSet.h` for one function `getUsedDebugRegs()`, which is
used only in one place.

According to `ClangBuildAnalyzer` (run solely on building LLVM, no other
projects) the second most expensive template to instantiate is the
`SmallSet::insert` method used in the `inline` implementation in
`getUsedDebugRegs()`:

```
**** Templates that took longest to instantiate:
554239 ms: std::unordered_map<int, int> (2826 times, avg 196 ms)
521187 ms: llvm::SmallSet<llvm::Register, 4>::insert (930 times, avg 560
ms)
...
```

By removing this method and putting its implementation in the one call
site we greatly reduce the template instantiation time and reduce the
number of includes.

When copying the implementation, I removed a check on `MO.getReg()` as
this is checked within `MO.isVirtual()`.

[clang][WebAssembly] Implement support for table types and builtins

This commit implements support for WebAssembly table types and
respective builtins. Table tables are WebAssembly objects to store
reference types. They have a large amount of semantic restrictions
including, but not limited to, only being allowed to be declared
at the top-level as static arrays of zero-length. Not being arguments
or result of functions, not being stored ot memory, etc.

This commit introduces the __attribute__((wasm_table)) to attach to
arrays of WebAssembly reference types. And the following builtins to
manage tables:

* ref __builtin_wasm_table_get(table, idx)
* void __builtin_wasm_table_set(table, idx, ref)
* uint __builtin_wasm_table_size(table)
* uint __builtin_wasm_table_grow(table, ref, uint)
* void __builtin_wasm_table_fill(table, idx, ref, uint)
* void __builtin_wasm_table_copy(table, table, uint, uint, uint)

This commit also enables reference-types feature at bleeding-edge.

This is joint work with Alex Bradbury (@asb).
