Sam Clegg ffd0aaf810 Revert "[WebAssembly] Error on mismatched function signature in final output" 
This caused a lot of issues on the WebAssembly waterfall.
In particular, until with the signature of `main`.  We
probably want a better solution for main before we re-land.

Sam Clegg 1369dfa30b [WebAssembly] Error on mismatched function signature in final output 
During symbol resolution, emit warnings for function signature
mismatches.  During GC, if any mismatched symbol is marked as live
then generate an error.

This means that we only error out if the mismatch is written to the
final output.  i.e. if we would generate an invalid wasm file.

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 fe78ccf1a1 [WebAssembly] Fix bug is function signature checking 
This bug effected undefined symbols that were resolved by
existing defined symbols.  We were skipping the signature
check in this case.

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.

Sam Clegg b862159683 [WebAssembly] Allow function signature checking at link time 
This change allows checking of function signatures but
does not yes enable it by default.  In this mode, linking
two objects that were compiled with a different signatures
for the same function will produce a link error.

New options for enabling and disabling this feature have been
added: (--check-signatures/--no-check-signatures).
