Sam Clegg caa0db1318 [lld][WebAssembly] Add optional symbols after input file handling 
This allows undefined references in input files be resolved by the
optional symbols.  Previously we were doing this before input file
reading which means it was working only for command line symbols
references (i.e. -u or --export).

Also use addOptionalDataSymbol for __dso_handle and make all optional
symbols hidden by default.

Sam Clegg 7d4ec5af6c [WebAssembly] Don't export __data_end and __heap_base by default. 
These can still be exported via --export if needed.
