There are a few tests that are listed as failing here for which I have
a patch in the works. I'll be sending those along soon. There are
others where I know what is going on but don't yet have a solution,
and I've included some notes for those. Several still need to be
investigated, mostly in localization and the regex test suite. I think
that many of these failures are due to locale implementation
variations that make the expected test results not match the actual
results. I'm not sure what the best way to make the tests accomodate
this sort of variation might be.

The failures in the unique_ptr test suite are very new and are caused
by a clang crash which I've not yet looked into.

Assuming infinite issue width, compute the earliest each instruction in
the trace can issue, when considering the latency of data dependencies.
The issue cycle is record as a 'depth' from the beginning of the trace.

This is half the computation required to find the length of the critical
path through the trace. Heights are next.

This also tidies up a couple of other tools we were (partially) installing:
* c-index-test was being installed but shouldn't be (it's just a clang-dev tool)
* diagtool was being installed in cmake but not make (& shouldn't be installed in either)

single-precision load and store.

Also avoid selecting LUXC1 and SUXC1 instructions during isel. It is incorrect
to map unaligned floating point load/store nodes to these instructions.

One motivating example is to sink an instruction from a basic block which has
two successors: one outside the loop, the other inside the loop. We should try
to sink the instruction outside the loop.

While usually we'd use a symbolic region rather than a straight-up Unknown,
we can still generate unknowns via array subscripts with symbolic indexes.
(And if this ever changes in the future, we still shouldn't crash.)

This was causing a crash in our array-to-pointer logic, since the region

First tiny move towards integrating AddressSanitizer regressions test into LLVM lit-based testing infrastructure.
The goal is to be able to run ASan tests by simply running "make check-asan" command from CMake build tree:
* tests should use fresh clang binary from current build tree.
* tests should use the same RUN-lines syntax as llvm/clang reg tests.

Next steps:
- restricting tests to machines where target is equal to host, i.e. where we can produce working binaries.
- moving AddressSanitizer unit tests to lit as well.

[Sanitizer] Wrapper around llvm::DIContext from LLVM DebugInfo library. If a macro SANITIZER_USES_LLVM_LIBS is defined (by default it is not), then sanitizer runtime includes llvm headers and tries to use LLVM libs for in-process symbolization. To make it functional, we have to link with these LLVM libs - either pass them to linker from Clang driver, or link them into static ASan runtime when we build it.
