5f3116636b Make SROA produce a vector only when the alloca is actually 
accessed at least once as a vector.  This prevents it from
compiling the example in not-a-vector into:

define double @test(double %A, double %B) {
	%tmp4 = insertelement <7 x double> undef, double %A, i32 0
	%tmp = insertelement <7 x double> %tmp4, double %B, i32 4
	%tmp2 = extractelement <7 x double> %tmp, i32 4
	ret double %tmp2
}

instead, producing the integer code.  Producing vectors when they
aren't otherwise in the program is dangerous because a lot of other
code treats them carefully and doesn't want to break them down.
OTOH, many things want to break down tasty i448's.

and that sroa doesn't crash.

87db26ad2c Fix PR3411. When replacing values, nodes are analyzed 
in any old order.  Since analyzing a node analyzes its
operands also, this can mean that when we pop a node
off the list of nodes to be analyzed, it may already
have been analyzed.

78decbdb9d Explicitly pass in the "unknown" debug location. This is probably not

cb9d033aa4 Delete these two tests. They are specific to x86-64, and there's no 
reliable way to do this with the current dejagnu infrastructure.
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.

2dae393299 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.

0103631cce 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.

2170150035 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.

9d2293f7ad MergeValueInto is too smart: it might choose to do the merge the opposite direction.
