This reverts commit 418df4a6ab35d343cc0f2608c90a73dd9b8d0ab1. This change broke emscripten tests, I believe because it started generating 5-byte a wide table index in the call_indirect instruction. Neither v8 nor wabt seem to be able to handle that. The spec currently says that this is single 0x0 byte and: "In future versions of WebAssembly, the zero byte occurring in the encoding of the call_indirectcall_indirect instruction may be used to index additional tables." So we need to revisit this change. For backwards compat I guess we need to guarantee that __indirect_function_table is always at address zero. We could also consider making this a single-byte relocation with and assert if have more than 127 tables (for now). Differential Revision: https://reviews.llvm.org/D95005
