The LTO/TM tests are failing with a type mismatch on x86-32 because of
the missing regparm on the prototype.
I have added the regparm, and abstracted things a bit so we don't have
to keep multiple copies. It's bad enough that we have to reproduce this
once...

This can be counter-productive, as the RETURN type is bigger and might not fit

This is a regression present on the mainline. The compiler aborts when trying

This one has probably been there since day #1: the layout of aliased components
