Looks like r161368 fixed this for one case but not all. This change generalizes
the solution over all the unwrapping cases. Now that preserving the qualifiers
is done independent of the particular type being unwrapped I won't bother
adding test cases for each one but at least demonstrate that this change was
necessary & sufficient to fix the bug.

lowered cost.

Currently, this is a direct port of the logic implementing
isInstructionFree in CodeMetrics. The hope is that the interface can be
improved (f.ex. supporting un-formed instruction queries) and the
implementation abstracted so that as we have test cases and target
knowledge we can expose increasingly accurate heuristics to clients.

I'll start switching existing consumers over and kill off the routine in
CodeMetrics in subsequent commits.

Michael, can this test be ported to C++03?

Capitalize lowerTRUNCATE so that it matches the other lower functions in this file despite it not matching coding standards.

It is not possible to distinguish 3r instructions from 2r / rus instructions
using only the fixed bits. Therefore if an instruction doesn't match the
2r / rus format try to decode it as a 3r instruction before returning Fail.

On valgrind the processor is reported;

FIXME: It could be removed if;

  - check-all included llvm/valgrind/supp, too.
  - clang-vg didn't use "check-all".

Add top-level Clang flag -f(no-)sanitize-address-zero-base-shadow that makes AddressSanitizer use bottom of the address space for the shadow memory. On Linux it can be used with -fPIE/-pie to improve performance.

Revert 172708.

The optimization handles esoteric cases but adds a lot of complexity both to the X86 backend and to other backends.
This optimization disables an important canonicalization of chains of SEXT nodes and makes SEXT and ZEXT asymmetrical.
Disabling the canonicalization of consecutive SEXT nodes into a single node disables other DAG optimizations that assume
that there is only one SEXT node. The AVX mask optimizations is one example. Additionally this optimization does not update the cost model.

Changed IRBuilder::CreateZExtOrTrunc and IRBuilder::CreateSExtOrTrunc so they also work with vectors.

I also changed the name of a variable in IRBuilder::CreateFPExtOrFPTrunc to
match the names used in its two matching brethern as well.

We ignore the cpu frontend and focus on pipeline utilization. We do this because we
don't have a good way to estimate the loop body size at the IR level.
