c17025abdc 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.

cb04139235 Use std::string instead of StringRef in ClangAttrEmitter.cpp; per report on

d6e0ffd95b Update local stack block allocation to let PEI do the allocs if no additional 
base registers were required. This will allow for slightly better packing
of the locals when alignment padding is necessary after callee saved registers.

4690ffd18a If any def of a machine-sink candidate has local uses, it's obviously not safe to sink it to a successor block. This bug has been hidden because a later check for critical-edge disable these illegal optimizations. This patch should significantly reduce the amount of time spent on checking dominator information for obviously unsafe sinking.

1e05823153 rework GEP decomposition to make a new VariableGEPIndex struct instead of 
using a pair.  This tidies up the code a bit.  While setting things up, add
a (currently unused) field to keep track of how the value is extended.

it's near enough to any previously allocaated base register to re-use.

95e334dbca Make raw_fd_ostream consider itself the owner of STDOUT_FILENO when 
constructed with an output filename of "-". In particular, allow the
file descriptor to be closed, and close the file descriptor in the
destructor if it hasn't been explicitly closed already, to ensure
that any write errors are detected.

bd80bd5d69 move gep decomposition out of ValueTracking into BasicAA. The form of 
decomposition that it is doing is very basicaa specific and is only used
by basicaa.
