This bug was found by accident while trying to expand out testcases
for imported symbols, and is covered by the additional test case.

This matches the existing ordering that's been there for globals
for a while (__stack_pointer coming first).

Update LLD test expectations for new symbol ordering introduced by
Differential D43685.

This means we don't need to write the linking metadata section
at all for executable (non-relocatable) output.

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.

This bug effected undefined symbols that were resolved by
existing defined symbols. We were skipping the signature
check in this case.

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.

When writing relocatable files we were exporting for all globals
(including file-local syms), but not for functions. Oops. To be
consistent with non-relocatable output, all symbols (file-local
and global) should be exported. Any symbol targetted by further
relocations needs to be exported. The lack of local function
exports was just an omission, I think.
Second bug: Local symbol names can collide, causing an illegal
Wasm file to be generated! Oops again. This only previously affected
producing relocatable output from two files, where each had a global
with the same name. We need to "budge" the symbol names for locals
that are exported on relocatable output.
Third bug: LLD's relocatable output wasn't writing out any symbol
flags! Thus the local globals weren't being marked as local, and
the hidden flag was also stripped...
Added tests to exercise colliding local names with/without
relocatable flag

This change add support for init functions in the linking
section, but only in -r/--relocatable mode.
