62a3f1538c - 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.

8d84d5b62c 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.

e46611e6bc 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.

b017c9e89c implement an initial hack at a straight-line store -> memset optimization. 
This fires dozens of times across spec and multisource, but I don't know
if it actually speeds stuff up.  Hopefully the testers will show something
nice :)
