c3c8db9d25 Teach AddressSanitizer to create basic blocks in a more natural order.
This is particularly useful to the backend code generators which try to
process things in the incoming function order.

Also, cleanup some uses of IRBuilder to be a bit simpler and more clear.

2f58533d1e Add a basic test for AddressSanitizer. This is just a bare-bones
functionality test.

In general, unless the functionality is substantially separated, we
should lump more basic testing into this file. The test running
infrastructure likes having a few test files with more comprehensive
testing within them.

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.

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.
