cfe33c46aa [AVX] Add INSERT_SUBVECTOR and support it on x86. This provides a 
default implementation for x86, going through the stack in a similr
fashion to how the codegen implements BUILD_VECTOR.  Eventually this
will get matched to VINSERTF128 if AVX is available.

91585098ef [AVX] Support EXTRACT_SUBVECTOR on x86. This provides a default 
implementation of EXTRACT_SUBVECTOR for x86, going through the stack
in a similr fashion to how the codegen implements BUILD_VECTOR.
Eventually this will get matched to VEXTRACTF128 if AVX is available.

37f87c7aa9 Fix PR9039, a use-after-free in reassociate. The issue was that the 
operand being factorized (and erased) could occur several times in Ops,
resulting in freed memory being used when the next occurrence in Ops was
analyzed.

207c193e7e Teach mergefunc that intptr_t is the same width as a pointer. We still can't 
merge vector<intptr_t>::push_back() and vector<void*>::push_back() because
Enumerate() doesn't realize that "i64* null" and "i8** null" are equivalent.

e19b7b80bd Fix memory corruption. If one of the SCEV creation functions calls another but 
doesn't return immediately after then the insert position in UniqueSCEVs will
be out of date. No test because this is a memory corruption issue. Fixes PR9051!

d70d1a5c44 According to my auto-simplifier the most common missed simplifications in 
optimized code are:
  (non-negative number)+(power-of-two) != 0 -> true
and
  (x | 1) != 0 -> true
Instcombine knows about the second one of course, but only does it if X|1
has only one use.  These fire thousands of times in the testsuite.
