`--no-demangle` now also applies to the name section. This change
was motivated by the rust team that have a slightly different name
mangling scheme to the standard C++ itanium one and prefer to do their
de-mangling as a post-link setp.

In a very recent change I introduced a --no-export-default flag
but after conferring with others it seems that this feature already
exists in gnu GNU ld and lld in the form the --export-dynamic flag
which is off by default.
This change replaces export-default with export-dynamic and also
changes the default to match the traditional linker behaviour.
Now, by default, only the entry point is exported. If other symbols
are required by the embedder then --export-dynamic or --export can
be used to export all visibility hidden symbols or individual
symbols respectively.
This change touches a lot of tests that were relying on symbols
being exported by default. I imagine it will also effect many
users but do think the change is worth it match of the traditional
behaviour and flag names.

This matches the behavior of the ELF linker where -u/--undefined
means symbols will get pulled in from archives but won't result
in link error if they are missing.
Also, don't actually great symbol table entries for the undefined
symbols, again matching more closely the ELF linker.
This also results in simplification of the code.
