[WebAssembly] Improve wasm test cases Add test for weakly defined symbols with the same name Improve test for call-indirect to include the same call in two different objects. This lays the ground work to improve the output via de-duplicating the indirect call table: https://reviews.llvm.org/D40989 Also make all tests consistently pass -mtriple rather than declaring in the sources.

[WebAssembly] Initial wasm linker implementation This linker backend is still a work in progress but is enough to link simple programs including linking against library archives. Differential Revision: https://reviews.llvm.org/D34851 llvm-svn: 318539

[WebAssembly] Fix symbol exports under -r/--relocatable This change cleans up the way wasm exports and globals are generated, particualrly for -r/--relocatable where globals need to be created and exported in order for output relocations which reference them. Remove the need for a per file GlobalIndexOffset and instead set the output index for each symbol directly. This simplifies the code in several places.
