4bbf4678e3 Improve pre-RA-sched register pressure tracking for duplicate operands. 
This helps cases like 2008-07-19-movups-spills.ll, but doesn't have an obvious impact on benchmarks

e62289b98f When SCEV can determine the loop test is X < X, set ExactBECount=0. 
When ExactBECount is a constant, use it for MaxBECount.
When MaxBECount cannot be computed, replace it with ExactBECount.
Fixes PR9424.

84dd4fa2e3 Add another micro-optimization. Apologies for the lack of refactoring, but I 
gave up when I realized I couldn't come up with a good name for what the
refactored function would be, to describe what it does.

This is PR9343 test12, which is test3 with arguments reordered. Whoops!

b2fd770136 Add support to scalar replacement for partial vector accesses of an alloca, e.g. 
a union of a float, <2 x float>, and <4 x float>. This mostly comes up with the
use of vector intrinsics, especially in NEON when programmers know the layout of
the register file. This enables codegen to eliminate a lot of the subregister
traffic it would otherwise generate.

This commit only enables this for a small number of floating-point cases, but a
lot more integer cases. I assume this is okay for all ports, but I did not do
extensive testing of the quality of code involving i512 vectors and the like. If
there is a use case where this generates worse code than before, let me know and
we can scale it back.

This fixes <rdar://problem/9036264>.

2adc5b6a17 PR9420; an instruction before an unreachable is guaranteed not to have any 
reachable uses, but there still might be uses in dead blocks.  Use the
standard solution of replacing all the uses with undef.  This is
a rare case because it's very sensitive to phase ordering in SimplifyCFG.

29449448b0 Fix some latent bugs if the nodes are unschedulable. We'd gotten away

had unschedulable nodes.

This should probably be refixed with a special default Node that just
returns some "don't touch me" values.
