Fix x86 fast-isel's cmp+branch folding to avoid folding when the
comparison is in a different basic block from the branch. In such
cases, the comparison's operands may not have initialized virtual
registers available.

This is the first step towards refactoring the x86 vector shuffle code. The
general idea here is to have a group of x86 target specific nodes which are
going to be selected during lowering and then directly matched in isel.

The commit includes the addition of those specific nodes and a *bunch* of
patterns, and incrementally we're going to switch between them and what we
have right now. Both the patterns and target specific nodes can change as
we move forward with this work.

Create the new linker type "linker_private_weak_def_auto".

It's similar to "linker_private_weak", but it's known that the address of the
object is not taken. For instance, functions that had an inline definition, but
the compiler decided not to inline it. Note, unlike linker_private and
linker_private_weak, linker_private_weak_def_auto may have only default
visibility.  The symbols are removed by the linker from the final linked image
(executable or dynamic library).

If the target says that an extending load is not legal, regardless of whether
it involves specific floating-point types, legalize should expand an
extending load to a non-extending load followed by a separate extend operation.
For example, we currently expand SEXTLOAD to EXTLOAD+SIGN_EXTEND_INREG (and
assert that EXTLOAD should always be supported).  Now we can expand that to
LOAD+SIGN_EXTEND.  This is needed to allow vector SIGN_EXTEND and ZERO_EXTEND
to be used for NEON.

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.

Use std::string instead of StringRef in ClangAttrEmitter.cpp; per report on
cfe-dev, fixes an error compiling with MSVC.  Using a StringRef here doesn't
look safe in any case.

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.
