Dale Johannesen 58698d2534 More effective breakdown of memcpy into repeated load/store. These are now 
in the order lod;lod;lod;sto;sto;sto which means the load-store optimizer
has a better chance of producing ldm/stm.  Ideally you would get cooperation
from the RA as well but this is not there yet.

Dan Gohman 26b4ef76d9 Fix some sporadic segfaults that are triggered when SmallVector's heap 
storage lands near the end of the available address space. In the expression
Begin+N > Capacity, the Begin+N was overflowing. Fix this by replacing it
by with an expression that doesn't involve computation of an address
beyond the end of allocated memory.
