[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

[WebAssembly] Add missing function exports and SYM_INFO to --relocatable output When writing relocatable files we were exporting for all globals (including file-local syms), but not for functions. Oops. To be consistent with non-relocatable output, all symbols (file-local and global) should be exported. Any symbol targetted by further relocations needs to be exported. The lack of local function exports was just an omission, I think. Second bug: Local symbol names can collide, causing an illegal Wasm file to be generated! Oops again. This only previously affected producing relocatable output from two files, where each had a global with the same name. We need to "budge" the symbol names for locals that are exported on relocatable output. Third bug: LLD's relocatable output wasn't writing out any symbol flags!

[WebAssembly] Add missing function exports and SYM_INFO to --relocatable output When writing relocatable files we were exporting for all globals (including file-local syms), but not for functions. Oops. To be consistent with non-relocatable output, all symbols (file-local and global) should be exported. Any symbol targetted by further relocations needs to be exported. The lack of local function exports was just an omission, I think. Second bug: Local symbol names can collide, causing an illegal Wasm file to be generated! Oops again. This only previously affected producing relocatable output from two files, where each had a global with the same name. We need to "budge" the symbol names for locals that are exported on relocatable output. Third bug: LLD's relocatable output wasn't writing out any symbol flags! Thus the local globals weren't being marked as local, and the hidden flag was also stripped... Added tests to exercise colliding local names with/without relocatable flag Patch by Nicholas Wilson!
