[WebAssembly] call_indirect issues table number relocs

This patch changes to make call_indirect explicitly refer to the
corresponding function table, residualizing TABLE_NUMBER relocs against

With this change, wasm-ld now sees all references to tables, and can
link multiple tables.

[WebAssembly] Change prefix on data segment flags to WASM_DATA_SEGMENT

Element sections will also need flags, so we shouldn't squat the
WASM_SEGMENT namespace.

Depends on D90948.

[clang][cli] Parse Lang and CodeGen options separately

This patch moves the parsing of `{Lang,CodeGen}Options` from `parseSimpleArgs` to the original `Parse{Lang,CodeGen}Args` functions.

This ensures all marshalled `LangOptions` are being parsed **after** the call `setLangDefaults`, which in turn enables us to marshall `LangOptions` that somehow depend on the defaults. (In a future patch.)

Now, `CodeGenOptions` need to be parsed **after** `LangOptions`, because `-cl-mad-enable` (a `CodeGenOpt`) depends on the value of `-cl-fast-relaxed-math` and `-cl-unsafe-math-optimizations` (`LangOpts`).

Unfortunately, this removes the nice property that marshalled options get parsed in the exact order they appear in the `.td` file. Now we cannot be sure that a TableGen record referenced in `ImpliedByAnyOf` has already been parsed. This might cause an ordering issues (i.e. reading value of uninitialized variable). I plan to mitigate this by moving each `XxxOpt` group from `parseSimpleArgs` back to their original parsing function. With this setup, if an option from group `A` references option from group `B` in TableGen, the compiler will require us to make the `CompilerInvocation` member for `B` visible in the parsing function for `A`. That's where we notice that `B` didn't get parsed yet.

[NFC] Make remaining cost functions in LoopVectorize.cpp use InstructionCost

A previous patch has already changed getInstructionCost to return
an InstructionCost type. This patch changes the other various
getXXXCost functions to return an InstructionCost too. This is a
non-functional change - I've added a few asserts that the costs
are valid in places where we're selecting between vector call
and intrinsic costs. However, since we don't yet return invalid
costs from any of the TTI implementations these asserts should
not fire.

See this patch for the introduction of the type:
See this thread for context:
