f4948450d1 patch 69408 breaks this by removing the opportunity 
for the optimization it's testing to kick in (although
it improves the code, getting rid of all spills).
I don't understand the optimization well enough to
rescue the test, so XFAILing.

276b77e66c Teach spiller to unfold instructions which modref spill slot when a scratch 
register is available and when it's profitable.

e.g.
     xorq  %r12<kill>, %r13
     addq  %rax, -184(%rbp)
     addq  %r13, -184(%rbp)
==>
     xorq  %r12<kill>, %r13
     movq  -184(%rbp), %r12
     addq  %rax, %r12
     addq  %r13, %r12
     movq  %r12, -184(%rbp)

Two more instructions, but fewer memory accesses. It can also open up
opportunities for more optimizations.

d305e707a6 Fix PR3994: LLVMMatchType arguments do not refer to absolute return value 
and argument positions but only to the overloaded intrinsic parameters.
Keep a separate list of these overloaded parameters in CodeGenTarget.cpp
so they can be resolved easily.  Remove assertions from IntrinsicEmitter.cpp:
they were harmless but confusing, and the assertions elsewhere in TableGen
will catch any incorrect values.

2d1be87ee4 Expand GEPs in ScalarEvolution expressions. SCEV expressions can now 
have pointer types, though in contrast to C pointer types, SCEV
addition is never implicitly scaled. This not only eliminates the
need for special code like IndVars' EliminatePointerRecurrence
and LSR's own GEP expansion code, it also does a better job because
it lets the normal optimizations handle pointer expressions just
like integer expressions.

Also, since LLVM IR GEPs can't directly index into multi-dimensional
VLAs, moving the GEP analysis out of client code and into the SCEV
framework makes it easier for clients to handle multi-dimensional
VLAs the same way as other arrays.

Some existing regression tests show improved optimization.
test/CodeGen/ARM/2007-03-13-InstrSched.ll in particular improved to
the point where if-conversion started kicking in; I turned it off
for this test to preserve the intent of the test.
