Previously, we were using EBX, but PIC requires the GOT to be in EBX before 
function calls via PLT GOT pointer.

For now this will stay on, but this way it's easy to switch off if we need
to pull back our support for a while.

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.)

scanf. Ignore the volatile qualifier when checking if types match.

This was causing a crash in our array-to-pointer logic, since the region
was clearly not an array.

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.

Clear the FileManager's stat cache in between running

[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.
