Clemens Backes 614f62d8a1 [turbofan] Use movl for reloading 32-bit values
This enables an optimization for JavaScript which is currently only
enabled for WebAssembly. Clusterfuzz found problems on a previous try to
enable this (see https://crbug.com/1356461), but a fix
(https://crrev.com/c/4197349) landed in the meantime which might have
fixed things.
Any resulting crashes or other issues will have to be fixed before the
v11.2 branch cut, otherwise we will have to revert this CL.
