[WebAssembly] Define call-indirect-overlong and bulk-memory-opt features (#117087)
This defines some new target features. These are subsets of existing
features that reflect implementation concerns:
- "call-indirect-overlong" - implied by "reference-types"; just the
overlong encoding for the `call_indirect` immediate, and not the actual
reference types.
- "bulk-memory-opt" - implied by "bulk-memory": just `memory.copy` and
`memory.fill`, and not the other instructions in the bulk-memory
proposal.
This is split out from https://github.com/llvm/llvm-project/pull/112035.

[WebAssembly] call_indirect issues table number relocs
If the reference-types feature is enabled, call_indirect will explicitly
reference its corresponding function table via TABLE_NUMBER
relocations against a table symbol.
Also, as before, address-taken functions can also cause the function
table to be created, only with reference-types they additionally cause a
symbol table entry to be emitted.

Also, as before, address-taken functions can also cause the function

We abuse the used-in-reloc flag on symbols to indicate which tables
should end up in the symbol table. We do this because unfortunately
older wasm-ld will carp if it see a table symbol.

Revert "[WebAssembly] call_indirect issues table number relocs"
This reverts commit 418df4a6ab35d343cc0f2608c90a73dd9b8d0ab1.
This change broke emscripten tests, I believe because it started
generating 5-byte a wide table index in the call_indirect instruction.
Neither v8 nor wabt seem to be able to handle that. The spec
currently says that this is single 0x0 byte and:
"In future versions of WebAssembly, the zero byte occurring in the
encoding of the call_indirectcall_indirect instruction may be used to
index additional tables."
So we need to revisit this change. For backwards compat I guess
we need to guarantee that __indirect_function_table is always at
address zero. We could also consider making this a single-byte
relocation with and assert if have more than 127 tables (for now).

[lld][WebAssembly] Convert some lld tests to assembly
When we originally wrote these tests we didn't have a stable and
fleshed out assembly format. Now we do so we should prefer that
over llvm ir for lld tests to avoid including more part of llvm
than necessary in order to run the test.
This change converts just 30 out of about 130 test files. More to
come when I have some more time.

[WebAssembly] Add --[no]-export-dynamic to replace --export-default
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.

[WebAssembly] Add option to remove LEB padding at relocate sites
This change adds the ability for lld to remove LEB padding from
code section. This effectively shrinks the size of the resulting
binary in proportion to the number of code relocations.
Since there will be a performance cost this is currently only active for
-O1 and above. Some toolchains may instead want to perform this
compression as a post linker step (for example running a binary through
binaryen will automatically compress these values).
I imagine we might want to make this the default in the future.
