848de0c1c5 The 'false.c' test must depend on llvm-g++. 
Also, turn on Objective-C/C++ tests.
This should fix http://llvm.org/bugs/show_bug.cgi?id=3499.

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.

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.

b47738daab Teach ConvertUsesToScalar to handle memset, allowing it to handle 
crazy cases like:

  struct f A;
  A.A = 1;
  memset(&A.B, 2, 12);
  return A.C;

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.
