2594ddf452 Mark llvm.stacksave as only reading memory, this fixes 
Regression/Transforms/InstCombine/stacksaverestore.ll

7c2afcfc02 Fix PR681 by using the standard Lengauer and Tarjan algorithm for dominator 
set construction, rather than intersecting various std::sets.  This reduces
the memory usage for the testcase in PR681 from 496 to 26MB of ram on my
darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a
2.5GHz G5.  This also enables future code sharing between Dom and PostDom
now that they share near-identical implementations.

off the result string at the first null terminator.
