[PR 91831] Copy PARM_DECLs of artificial thunks

Hi,

I am quite surprised I did not catch this before but the new
ipa-param-manipulation does not copy PARM_DECLs when creating
artificial thinks (I think it originally did but then I somehow
removed during one cleanups).  Fixed by adding the capability at the
natural place.  It is triggered whenever context of the PARM_DECL that
is just taken from the original function does not match the target
fndecl rather than by some constructor parameter because in such
situation it is always the correct thing to do.

Bootstrapped and tested on x86_64-linux.  OK for trunk?

Thanks,

Martin
