[WebAssembly] Implementation of table.get/set for reftypes in LLVM IR This change implements new DAG nodes TABLE_GET/TABLE_SET, and lowering methods for load and stores of reference types from IR arrays. These global LLVM IR arrays represent tables at the Wasm level. Differential Revision: https://reviews.llvm.org/D111154

[WebAssembly] Refactor and fix emission of external IR global decls Reland of 00bf4755. This patches fixes the visibility and linkage information of symbols referring to IR globals. Emission of external declarations is now done in the first execution of emitConstantPool rather than in emitLinkage (and a few other places). This is the point where we have already gathered information about used symbols (by running the MC Lower PrePass) and not yet started emitting any functions so that any declarations that need to be emitted are done so at the top of the file before any functions. This changes the order of a few directives in the final asm file which required an update to a few tests. Reviewed By: sbc100 Differential Revision: https://reviews.llvm.org/D118995
