Some minor tweaks to make our use of the allocation entrypoints

Browse Source 
match the actual entrypoints vended by the runtime:
1) there is no swift_slowRawAlloc
2) swift_deallocObject takes two arguments
Also, make all calls to swift_allocObject go through a common
function so that we can easily use optimized entrypoints if the
runtime provides them.
