c-family: attribute ((aligned, mode)) [PR100545]
The problem here was that handle_mode_attribute clobbered the changes of any
previous attribute, only copying type qualifiers to the new type. And
common_handle_aligned_attribute had previously set up the typedef, so when
we later called set_underlying_type it saw DECL_ORIGINAL_TYPE set and just
returned, even though handle_mode_attribute had messed up the TREE_TYPE.
So, let's fix handle_mode_attribute to copy attributes, alignment, and
typedefness to the new type.
