Thomas Lively 2e1504091e [WebAssembly] Update MC for bulk memory 
Summary:
Rename MemoryIndex to InitFlags and implement logic for determining
data segment layout in ObjectYAML and MC. Also adds a "passive" flag
for the .section assembler directive although this cannot be assembled
yet because the assembler does not support data sections.

Sam Clegg 99eb42c0c5 [WebAssembly] Remove DataSize from linking metadata 
This means we don't need to write the linking metadata section

Sam Clegg 9310297438 [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.

Rui Ueyama f05124e60c Use wasm-ld instead of "lld -flavor wasm". 
Invoking lld as ld.lld, ld.ld64, lld-link or wasm-ld is preferred
than invoking lld as lld and pass an -flavor option. We have "lld"
file mostly for historical reasons.

Sam Clegg 70683b2f75 [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.

Sam Clegg 2e25e896fb [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.
