please consider .einline2 and .optimized trees for the
boost::thread::start_thread() function from attached testcase.

the 4.3 optimize boost::shared_ptr<>::operator= pretty nice.
the 4.5 avoid operator= inlining.

moreover, the 4.5 code is bigger (152bytes vs 106bytes)
and contains more atomic operations due to temporary shared_ptr
swapping and assignments.

the testcase is big and horrible but the 'pretty 4.3 inlining'
dissapears during testcase reducing :/
