e191a19b69 Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock: 
don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.

Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.

This fixes a major compile-time bottleneck which is exposed now that
LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.

a0b74d8804 Add an ILP scheduler. This is a register pressure aware scheduler that's 
appropriate for targets without detailed instruction iterineries.
The scheduler schedules for increased instruction level parallelism in
low register pressure situation; it schedules to reduce register pressure
when the register pressure becomes high.

On x86_64, this is a win for all tests in CFP2000. It also sped up 256.bzip2
by 16%.

4b7545413d Use the appropriate register class for an i32 when adding ARM::LR to the 
function live in set. This will give us tGPR for Thumb1 and GPR otherwise,
so the copy will be spillable. rdar://8224931

30d0fca117 Remove too-strict assertion. We may want the vreg copy of the physical register 
to be of a different register class. For example, in Thumb1 if the live-in is
a high register, we want the vreg to be a low register. rdar://8224931

50d2bc2942 Revert 109076. It is wrong and was causing regressions. Add some 
comments explaining why it was wrong.  8225024.

Fix the real problem in 8213383: the code that splits very large
blocks when no other place to put constants can be found was not
considering the case that the block contained a Thumb tablejump.

f215e55d5f - Allow target to specify when is register pressure "too high". In most cases, 
it's too late to start backing off aggressive latency scheduling when most
  of the registers are in use so the threshold should be a bit tighter.
- Correctly handle live out's and extract_subreg etc.
- Enable register pressure aware scheduling by default for hybrid scheduler.
  For ARM, this is almost always a win on # of instructions. It's runtime
  neutral for most of the tests. But for some kernels with high register
  pressure it can be a huge win. e.g. 464.h264ref reduced number of spills by
  54 and sped up by 20%.
