bf3c8b8ff3 [wasm] Cleanup wasm-module-builder.js
Use naming similar to the spec: "table" instead of "function table",
"element segment" instead of "function table init".

903d87312e [wasm] Fix target instance for indirect calls to imports
In the case of an indirect call to an imported function, the target
instance stored in the IFT was actually wrong.

c536ea2dba [wasm] Remove temporary table immutability workaround
Now that tables and stack frames properly root instances, there is no
longer any need to disallow mutations that could unroot instances
while their code is on the stack.

0c1b4c257b [wasm] Move indirect function tables into the WasmContext
This CL changes the WASM implementation to access indirect function
tables through the WasmContext, whereas previously indirect function
tables and their sizes were constants that were inlined into compiled
into code, requiring code patching. This is a necessary step for sharing
code between instances and eventually, isolates.

883db26e6f [wasm] Update signature map on indirect calls
The code was already there, but there was a bug in it: Because of the
missing reference, we were only updating a *copy* of the signature map,
hence the update had no effect.
This intentially is a minimal CL, in order to allow for easy
backmerging.
More mitigations and tests are coming in a separate CL.

f29cae45ce [wasm] Fix emitting element section in wasm-module-builder.js
We were emitting the table index once in the element section instead of
once per element segment. This did not cause failures because we never
had more than one element segment.
This CL fixes this, and adds a test for more than one segment.
