Fix the msvc 2010 build.
...
The Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.30319.01
implements parts of C++0x based on the draft standard. An old version of
the draft had a bug that makes std::pair<T1*, T2*>(something, 0) fail to
compile. This is because the template<class U, class V> pair(U&& x, V&& y)
constructor is selected, even though it later fails to implicitly convert
U and V to frist_type and second_type.
This has been fixed in n3090, but it seems that Microsoft is not going to
update msvc.

If any def of a machine-sink candidate has local uses, it's obviously not safe to sink it to a successor block.

This patch should significantly reduce the amount of time spent on checking dominator information for obviously unsafe sinking.
