Use a simple recursive bash function to search for svn repos for the 'make
update' target thus including projects like clang-tools-extra.

We want to remove AttributeWithIndex because it provides a non-encapsulated view
of the AttributeSetImpl object. Instead, use accessor methods and iterators.

Eventually, this code can be simplified because the Attribute object will hold
only one attribute instead of multiple attributes.

Push the calculation of the 'Raw' attribute mask down into the implementation. It in turn uses the correct list for calculating the 'Raw' value.

Add special 'get' methods to create an Attribute with an alignment. Also do some random cleanup. No functionality change.

When flipping the pair of subvectors that form a vector, if the
vector length is 2, we can use the SK_Reverse shuffle kind to get
more-accurate cost information. Also we can use the SK_ExtractSubvector
shuffle kind to get accurate subvector extraction costs.

The current cost model implementations don't yet seem complex enough
for this to make a difference (thus, there are no test cases with this
commit), but it should help in future.

Depending on how the various targets optimize and combine shuffles in
practice, we might be able to get more-accurate costs by combining the
costs of multiple shuffle kinds. For example, the cost of flipping the
subvector pairs could be modeled as two extractions and two subvector
insertions. These changes, however, should probably be motivated
by specific test cases.

For example,
cur) unittests/ADT/Release/ADTTests
new) unittests/ADT/ADTTests

RUNTIME_BUILD_MODE can be substituted to CMAKE_CFG_INTDIR.

With Make and Ninja, the tree is not built with multiple configurations.
Then, including the build type in target directory doesn't make sense.
See also "How can I build multiple modes without switching?"
http://www.cmake.org/Wiki/CMake_FAQ
CMAKE_CFG_INTDIR is set to "."

With multiple-configuration-aware build system, like Visual Studio, each unittest is built on appropriate directory, for example,
unittests/ADT/Release/ADTTests.exe
CMAKE_CFG_INTDIR is set to build system's variable, like "$(Configuration)" or "$(OutDir)".

Thus, "--param build_config" is also deprecated.

Fix that by adding a cast to the shift expander. This came up with vector shifts
on sse-less X86 CPUs.

   <2 x i64>       = shl <2 x i64> <2 x i64>
-> i64,i64         = shl i64 i64; shl i64 i64
-> i32,i32,i32,i32 = shl_parts i32 i32 i64; shl_parts i32 i32 i64

Now we cast the last two i64s to the right type. Fixes the crash in PR14668.

This name change does the following:

1. Causes the function name to use proper ARC terminology.
2. Makes it clear what the function truly does.

This method will go away once AttributeWithIndex goes away. In the meantime,
hide it from general use.

internals of the AttributeSet to outside users, which isn't goodness.
