1778513fa5 [asan] move x86-specific test to a separate X86 directory with a custom lit.local.cfg file

0f0c411079 Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed. 
Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches.

60ebb1947f ThreadSanitizer, a race detector. First LLVM commit. 
Clang patch (flags) will follow shortly.
The run-time library will also follow, but not immediately.

0ca032b03d The patch resolves the conflict between AddressSanitizer and load widening (GVN). 
The problem initially reported by Mozilla folks (http://code.google.com/p/address-sanitizer/issues/detail?id=20),
but it also prevents us from enabling LLVM bootstrap with AddressSanitizer.
