Running the 2 GCC compatibility testsuites between the unpatched and the 
patched compiled indeed shows that this part of MEMBER_TYPE_FORCES_BLK is now 
useless for the purpose it was initially defined.  Moreover, removing it 
doesn't trigger any new failure in the testsuite except in one corner case (a 
GNU extension); but that can be easily patched in ia64_function_arg.

I plan on submitting a patch to Steve and you next week.

Thanks for your feedback.
