[legacy] Align legacy drivers' __shared data to the maximum possible
Some drivers that still use the legacy-driver wrapper (tg3 in particular)
apparently do not specify their alignment constraints properly. This
hack forces any __shared data to be maximally aligned.
Note that this provides only 16-byte alignment; it is not possible to
request alignment to any greater than 16 bytes using
__attribute__((aligned)), since the relocation code will preserve only 16
byte alignment (and operation under -DKEEP_IT_REAL cannot preserve more
that 16 byte alignment).
Idea proposed by Tim Hockin <thockin@google.com>
