Switch GVN and memdep to use PHITransAddr, which correctly handles
...
phi translation of complex expressions like &A[i+1]. This has the
following benefits:
1. The phi translation logic is all contained in its own class with
a strong interface and verification that it is self consistent.
2. The logic is more correct than before. Previously, if intermediate
expressions got PHI translated, we'd miss the update and scan for
the wrong pointers in predecessor blocks. @phi_trans2 is a testcase
for this.
3. We have a lot less code in memdep.
We can handle phi translation across blocks of things like @phi_trans3,
which is pretty insane :).
This patch should fix the miscompiles of 255.vortex, and I tested it
with a bootstrap of llvm-gcc, llvm-test and dejagnu of course.

Introduce the "@llvm.dbg.value" debug intrinsic.
...
The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value.
An example:
call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2 )
Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0.
