[compiler] Ensure feedback vector before compiling.

[compiler] Ensure feedback vector before compiling.

This makes sure the type feedback vector is allocated and installed on
the SharedFunctionInfo before any of the compilers are being called.
Note that this now allows for an object state where a function is not
compiled but has a valid feedback vector is installed. This is working
as intended and supported by the rest of the system.

This is genuinely dead code. Drive-by fix unrelated to the rest.
