There is a known intended race here. This is a follow-up to r264805,
which disabled tsan instrumentation for updates to instrprof counters.
For more background on this please see the discussion in D18164.

Summary: Inliner needs ACT when calling InlineFunction. Instead of nullptr, we need to pass it in from SampleProfileLoader

We recently made MemorySSA own the walker it creates. As a part of this,
the MSSA test fixture was changed to have a `Walker*` instead of a
`unique_ptr<Walker>`. So, we no longer need to do `&*Walker` in order to
get a `Walker*`.

Specific instances of intrinsic calls may want to be convergent, such
as certain register reads but the intrinsic declaration is not.

The implicit operand is added by the initial instruction construction,
so this was adding an additional vcc use. The original one
was missing the undef flag the original condition had,
so the verifier would complain.

This will help sneak undefs past GVN into the DAG for
some tests.
Also add missing intrinsic for rsq_legacy, even though the node
was already selected to the instruction. Also start passing
the debug location to intrinsic errors.

Trying to expand short names with a relative path doesn't work, so this
first gets the module name to get a full path (which can still have short
names).

TargetLowering and DAGToDAG are used to combine ADDC, ADDE and UMLAL
dags into UMAAL. Selection is split into the two phases because it
is easier to match the two patterns at those different times.

Reduces a bit of code duplication and clarify where we are interested
just on position independence and no the location of the symbol.

After a store has been eliminated, when making sure that the
instruction iterator points to a valid instruction, dbg intrinsics are
now ignored as a new instruction.

This patch adds a function that corresponds to `fUDTAnon`
and use that to compute TPI hash values as the reference does.

On the surface, this might not look like it does anything... but
actually it brings in the declaration "extern template class
AnalysisManager<Loop>;", which suppresses the instantiation of the
constructor, which avoids the funny interaction between "extern
template" and -fvisibility-inlines-hidden.

Removing dead instructions requires remembering which operands have
already been removed. RecursivelyDeleteTriviallyDeadInstructions has
this logic, don't partially reimplement it in LoopIdiomRecognize.
