Sam Clegg 22cfe52398 [WebAssembly] Simplify check for emitting relocations
This is a small change I split of from a larger one
that simplifies the condition that need to be checked
when decided if we need to emit relocation and all the
things they depend on (symbols, etc).

Heejin Ahn 675147b54d [WebAssembly] Revert r319592 "Add support for visibility flag"
r319488 reportedly broke one of LLVM bots (ubuntu-gcc7.1-werror), and this patch
depends on that patch.
See http://lab.llvm.org:8011/builders/ubuntu-gcc7.1-werror/builds/3369 for
details.

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).

Rui Ueyama 7d5a13799a Use llvm::StringSet instead of std::set.
std::set is pretty slow. We generally prefer llvm::StringSet if we don't
need an sorted set.

Rui Ueyama e48f223ed6 Remove `else` or `break` after `fatal`. NFC.
fatal() does not return, so we don't need `else` or `break` after a call
of fatal.
