[lld][WebAssembly] Convert some lld tests to assembly When we originally wrote these tests we didn't have a stable and fleshed out assembly format. Now we do so we should prefer that over llvm ir for lld tests to avoid including more part of llvm than necessary in order to run the test. This change converts just 30 out of about 130 test files. More to come when I have some more time. Differential Revision: https://reviews.llvm.org/D80361

[wasm-ld] Add __global_base symbol to mark the value of --global-base Summary: This is needed for address sanitizer on Emscripten. As everything in memory starts at the value passed to --global-base, everything before that can be used as shadow memory. This symbol is added so that the library for the ASan runtime can know where the shadow memory ends and real memory begins. This is split from D63742.

[lld][WebAssembly] Add optional symbols after input file handling This allows undefined references in input files be resolved by the optional symbols. Previously we were doing this before input file reading which means it was working only for command line symbols references (i.e. -u or --export). Also use addOptionalDataSymbol for __dso_handle and make all optional symbols hidden by default. Differential Revision: https://reviews.llvm.org/D65920 llvm-svn: 368310
