Move WebAssemblyUtilities from Utils to the CodeGen library. It primarily deals in MIR layer types, so it really lives in the CodeGen library. Move a variety of other things around to try create better separation. See issue #64166 for more info on layering. Move llvm/include/CodeGen/WasmAddressSpaces.h back to llvm/lib/Target/WebAssembly/Utils. Differential Revision: https://reviews.llvm.org/D156472
Previously WebAssemblyCFGStackify, WebAssemblyInstrInfo, and WebAssemblyPeephole all had equivalent logic for this. Move it into a common helper in WebAssemblyUtilities.
This removes `exnref` type and `br_on_exn` instruction. This is effectively NFC because most uses of these were already removed in the previous CLs. Reviewed By: dschuff, tlively Differential Revision: https://reviews.llvm.org/D94041
This adds missing `select` instruction support and block return type support for reference types. Also refactors WebAssemblyInstrRef.td and rearranges tests in reference-types.s. Tests don't include `exnref` types, because we currently don't support `exnref` for `ref.null` and the type will be removed soon anyway.

Soon it will be disallowed to depend on MachineFunction state in the constructor. This was only being used to get the MachineRegisterInfo for an assert, which I'm not sure is necessarily worth it. I would think any missing defs would be caught by the verifier later instead.
Summary: Extends the multivalue call infrastructure to tail calls, removes all legacy calls specialized for particular result types, and removes the CallIndirectFixup pass, since all indirect call arguments are now fixed up directly in the post-insertion hook. In order to keep supporting pretty-printed defs and uses in test expectations, MCInstLower now inserts an immediate containing the number of defs for each call and call_indirect. The InstPrinter is updated to query this immediate if it is present and determine which MCOperands are defs and uses accordingly. Depends on D72902.

Summary: This is necessary and sufficient to get simple cases of multiple return working with multivalue enabled. More complex cases will require block and loop signatures to be generalized to potentially be type indices as well.

Summary: This is the first change to enable the TLI to be built per-function so that -fno-builtin* handling can be migrated to use function attributes. See discussion on D61634 for background. This is an enabler for fixing handling of these options for LTO, for example. This change should not affect behavior, as the provided function is not yet used to build a specifically per-function TLI, but rather enables that migration. Most of the changes were very mechanical, e.g. passing a Function to the legacy analysis pass's getTLI interface, or in Module level cases, adding a callback. This is similar to the way the per-function TTI analysis works. There was one place where we were looking for builtins but not in the context of a specific function. See FindCXAAtExit in lib/Transforms/IPO/GlobalOpt.cpp. I'm somewhat concerned my workaround could provide the wrong behavior in some corner cases. Suggestions welcome.

Summary: This clang-tidy check is looking for unsigned integer variables whose initializer starts with an implicit cast from llvm::Register and changes the type of the variable to llvm::Register (dropping the llvm:: where possible).

Summary: Implements direct and indirect tail calls enabled by the 'tail-call' feature in both DAG ISel and FastISel. Updates existing call tests and adds new tests including a binary encoding test.
