LLVM CodeGen emits references to external symbols that are never declared in LLVM IR level, so they have no declared signature. However, WebAssembly requires all functions be declared with signatures. This patch adds a table for providing signatures for known runtime libcalls that will be used in subsequent patches to emit declarations for such functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@295857 91177308-0d34-0410-b5e6-96231b3b80d8
