crazy cases like:

struct f {  int A, B, C, D, E, F; };
short test4() {
  struct f A;
  A.A = 1;
  memset(&A.B, 2, 12);
  return A.C;
}

correct. We need more infrastructure before we can get the DebugLoc info for
these instructions.

If someone can figure out how to fix these tests so that they test
what they are intended to test without spuriously failing on any
popular platforms, they are invited to reinstate them.

With the new world order, it can handle cases where the first
store into the alloca is an element of the vector, instead of
requiring the first analyzed store to have the vector type 
itself.  This allows us to un-xfail

so this makes LoadSDNode and StoreSDNode smaller. Also, it makes
FoldingSetNodeIDs for loads and stores two AddIntegers smaller.

SSE2, however it's possible to disable SSE2, and the subtarget support
code thinks that if 64-bit implies SSE2 and SSE2 is disabled then
64-bit should also be disabled. Instead, just mark all the 64-bit
subtargets as explicitly supporting SSE2.

Also, move the code that makes -march=x86-64 enable 64-bit support by
default to only apply when there is no explicit subtarget. If you
need to specify a subtarget and you want 64-bit code, you'll need to
select a subtarget that supports 64-bit code.

direct-initialization following a user-defined conversion can select
any constructor; it just can't employ any user-defined
conversions. So we ban those conversions and classify the constructor
call based on the relationship between the "from" and "to" types in
the conversion.
