initial PHI nodes of the machine function.

ba120aa5fa fix a bitcode reader bug where it can't handle extractelement correctly: 
the index of the value being extracted is always an i32.  This fixes PR3465

3d730f7453 Teach ConvertUsesToScalar to handle memset, allowing it to handle 
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;
}

ec37e98b3d Explicitly pass in the "unknown" debug location. This is probably not 
correct. We need more infrastructure before we can get the DebugLoc info for
these instructions.

7809ecd5b0 rearrange how SRoA handles promotion of allocas to vectors. 
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 
test/CodeGen/X86/vec_ins_extract.ll.

a7ce741ff0 Use the SubclassData field to hold ExtType, isTrunc, and MemIndexedMode 
information. This eliminates the need for the Flags field in MemSDNode,
so this makes LoadSDNode and StoreSDNode smaller. Also, it makes
FoldingSetNodeIDs for loads and stores two AddIntegers smaller.

f75e5b4d8c Change Feature64Bit to not imply FeatureSSE2. All x86-64 hardware has 
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.

5b93f6fa82 MergeValueInto is too smart: it might choose to do the merge the opposite direction. 
Live interval reconstruction needs to account for this, and scour its maps to
prevent dangling references.
