[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

[lld] Make tests calling llvm-ar more robust Some lit tests that call llvm-ar use the 'r' flag. If the target archive already exists and is in a corrupt state, this can cause the test to fail. We have added 'rm -f' calls before the llvm-ar calls to increase the robustness of the tests. Differential revision: https://reviews.llvm.org/D49184 llvm-svn: 338705

[WebAssembly] When loading libraries look for companion `.imports` file This allows libraries to supply a list of symbols which are allowed to be undefined at link time (i.e. result in imports). This method replaces the existing mechanism (-allow-undefined-file) used by the clang driver to allow undefined symbols in libc. For more on motivation for this see: https://github.com/WebAssembly/tool-conventions/issues/35 In the long run we hope to remove this features and instead include this information in the object format itself.

[WebAssembly] Add explicit symbol table This change modified lld to in response the llvm change which moved to a more explicit symbol table in the object format. Based on patches by Nicholas Wilson: 1. https://reviews.llvm.org/D41955 2. https://reviews.llvm.org/D42585 The primary difference that we see in the test output is that for relocatable (-r) output we now have symbol table which replaces exports/imports and globals.
