Sam Clegg 74fe0ba105 [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.

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).

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).
