    Reland "[wasm][liftoff][eh] Implement catch_all" · 30dd7b46
    Thibaud Michaud authored
    This is a reland of 6e234e9d
    Fix CFI by adding a BTI instruction at the start of the handler.
    
    Original change's description:
    > [wasm][liftoff][eh] Implement catch_all
    >
    > Inline a catch handler after each potentially throwing call. The handler
    > just merges values into the actual catch environment and then jumps to
    > the catch body.
    >
    > This automatically adds support for unwind, which also uses the
    > "CatchAll" interface method.
    >
    > Many tests can be written either with "catch" or with "catch_all".
    > Duplicate them to get coverage for both.
