22002efa15 A quick nm audit turned up several fixed tables and objects that were 
marked read-write. Use const so that they can be allocated in a
read-only segment.

8cb64d8e8b Handle a special case xor undef, undef -> 0. Technically this should be transformed to undef. But this is such a common idiom (misuse) we are going to handle it.

58ad056286 Add CMP32mr and friends to the load-unfolding table. Among 
other things, this allows the scheduler to unfold a load operand
in the 2008-01-08-SchedulerCrash.ll testcase, so it now successfully
clones the comparison to avoid a pushf+popf.

44ed585350 Extend the builder interface to use the new instruction positioning code. 
This adds support for instruction iterators, as well as rewriting the
builder code to use these new functions. This lets us eliminate the C
bindings for moving around the builder.

dbdf48276a - SSE4.1 extractfps extracts a f32 into a gr32 register. Very useful! Not. Fix the instruction specification and teaches lowering code to use it only when the only use is a store instruction.

d01a2a18f8 Increasing the inline limit from (overly conservative) 200 to 300. Given each BB costs 20 and each instruction costs 5, 200 means a 4 BB function + 24 instructions (actually less because caller's size also contributes to it). 
Furthermore, double the limit when more than 10% of the callee instructions are vector instructions. Multimedia kernels tend to love inlining.

55d8543211 Be sure to remove intervals after we've joined them. Also, remove some duplicated code. 
With this pass, StrongPHIElim can compile very simple testcases correctly.  There's still a ways
to go before it's ready for prime time, though.
