When truncated vector stores were being custom lowered in
VectorLegalizer::LegalizeOp(), the old (illegal) and new (legal) node pair
was not being added to LegalizedNodes list.  Instead of the legalized
result being passed to VectorLegalizer::TranslateLegalizeResult(),
the result was being passed back into VectorLegalizer::LegalizeOp(),
which ended up adding a (new, new) pair to the list instead.

This was causing an assertion failure when a custom lowered truncated
vector store was the last instruction a basic block and the VectorLegalizer
was unable to find it in the LegalizedNodes list when updating the
DAG root.

This will make it easier to turn on struct-path aware TBAA since the metadata
format will change.

The original idea was to implement it all on the driver, but to do that the
driver needs to know the sse level and to do that it has to know the default
features of a cpu.

Benjamin Kramer pointed out that if one day we decide to implement support for
' __attribute__ ((__target__ ("arch=core2")))', then the frontend needs to
keep its knowledge of default features of a cpu.

To avoid duplicating which part of clang handles default cpu features,
it is probably better to handle -mfpmath in the frontend.

For ARM this patch is just a small improvement. Instead of a cpu list, we
check if neon is enabled, which allows us to reject things like

-mcpu=cortex-a9 -mfpu=vfp -mfpmath=neon

For X86, since LLVM doesn't support an independent ssefp feature, we just
make sure the selected -mfpmath matches the sse level.

The small utility function that pattern matches Base + Index +
Offset patterns for loads and stores fails to recognize the base
pointer for loads/stores from/into an array at offset 0 inside a
loop. As a result DAGCombiner::MergeConsecutiveStores was not able
to merge all stores.

This commit fixes the issue by adding an additional pattern match
and also a test case.

Summary:
This support will be utilized in things like clang to help check printf
format specifiers that are only valid when using the VSCRT.

With r185721, calling mangleCXXRTTIName on C code will cause crashes.
This commit fixes crashes on C testing cases when turning on struct-path TBAA.

For C code, we simply use the Decl name without the context. This can
cause two different structs having the same name, and may cause inaccurate but
conservative alias results.

[CMake] Automatically pick up subdirectories in llvm/tools as 'external projects' if they contain a 'CMakeLists.txt' file.

Allow CMake to pick up external projects in llvm/tools without the need to modify the "llvm/tools/CMakeLists.txt" file.
This makes it easier to work with projects that live in other repositories, without needing to specify each one in "llvm/tools/CMakeLists.txt".
