[WebAssembly] Add COMDAT support See https://bugs.llvm.org/show_bug.cgi?id=35533, and D40844 Things covered: * Removing duplicate data segments (as determined by COMDATs emitted by the frontend) * Removing duplicate globals and functions in COMDATs * Checking that each time a COMDAT is seen it has the same symbols as at other times (ie it's a stronger check than simply giving all the symbols in the COMDAT weak linkage) Patch by Nicholas Wilson!

[WebAssembly] Add --[no]-export-dynamic to replace --export-default In a very recent change I introduced a --no-export-default flag but after conferring with others it seems that this feature already exists in gnu GNU ld and lld in the form the --export-dynamic flag which is off by default. This change replaces export-default with export-dynamic and also changes the default to match the traditional linker behaviour. Now, by default, only the entry point is exported. If other symbols are required by the embedder then --export-dynamic or --export can be used to export all visibility hidden symbols or individual symbols respectively. This change touches a lot of tests that were relying on symbols being exported by default. I imagine it will also effect many users but do think the change is worth it match of the traditional behaviour and flag names. Differential Revision: https://reviews.llvm.org/D52587 llvm-svn: 343265

[WebAssembly] Use inline target tripple in test cases This is somewhat preferable since (in many cases) it allows llc to be run directly on the .ll files without having to pass the `-mtriple` argument. Differential Revision: https://reviews.llvm.org/D42438 llvm-svn: 323299
