[Patch, fortran] PR46897 - [OOP] type-bound defined ASSIGNMENT(=) not used for derived type component in intrinsic assign

[Paul Richard Thomas]

Dear All,

Please find attached a patch and testcase for the above PR.  The
comment before generate_component_assignments explains the need for
the patch, which itself is fairly self explanatory.

Bootstrapped and regtested on Fc9/x86_64 - OK for trunk?

Best regards

Paul and Alessandro.
