Some of the the permissible ARM -mfpu options, which are supported in GCC,
are currently not present in llvm/clang.This patch adds the options:
'neon-fp16', 'vfpv3-fp16', 'vfpv3-d16-fp16', 'vfpv3xd' and 'vfpv3xd-fp16.

AsmPrinter: Document why DIEValueList uses a linked-list, NFC

There are two main reasons why a linked-list makes sense for
`DIEValueList`.

 1. We want `DIE` to be on a `BumpPtrAllocator` to improve teardown
    efficiency.  Making `DIEValueList` array-based would make that much
    more complicated.
 2. The singly-linked list is fairly memory efficient.  The histogram
    [1] shows that most DIEs have relatively few values, so we often pay
    less than the 2/3-pointer static overhead of a vector.  Furthermore,
    we don't know ahead of time exactly how many values a `DIE` needs,
    so a vector-like scheme will on average over-allocate by ~50%.  As
    it happens, that's the same memory overhead as the linked list node.

IR: Expose ModuleSlotTracker in Value::print()

module-level slots (such as Metadata).

This is related to PR23865, where there was a huge cost for
`MachineFunction::print()`.  Although I don't have a *particular* user
in mind for this new code, I have hit big slowdowns before when running

someone hits a big slowdown with `print()` statements, they can create a
`ModuleSlotTracker` and send it through.  Similarly, adding support to
`Value::dump()` and `Metadata::dump()` should be trivial.

I added unit tests to be sure the `print()` functions actually behave
the same way with and without the slot tracker.

LowerBitSets: Ignore bitset entries that do not directly refer to a global.

It is possible for a global to be substituted with another global of a
different type or a different kind (i.e. an alias) at IR link time. One
example of this scenario is when a Microsoft ABI vtable is substituted with
an alias referring to a larger vtable containing an RTTI reference.

This will cause the global to be RAUW'd with a possibly bitcasted reference
to the other global. This will of course also affect any references to the
global in bitset metadata.

The right way to handle such metadata is simply to ignore it. This is sound
because the linked module should contain another copy of the bitset entries as
applied to the new global.

[RewriteStatepointsForGC] Generalized vector phi/select handling for base pointers

This change extends the detection of base pointers for vector constructs to handle arbitrary phi and select nodes. The existing non-vector code already handles those, so this is basically just extending the vector special case to be less special cased. It still isn't generalized vector handling since we can't handle arbitrary vector instructions (e.g. shufflevectors), but it's a lot closer.

The general structure of the change is as follows:
 * Extend the base defining value relation over a subset of vector instructions and vector typed phi & select instructions.
 * Move scalarization from before base pointer rewriting to after base pointer rewriting. The extension of the BDV relation is sufficient to find vector base phis for vector inputs.
 * Preserve the existing special case logic for when the base of a vector element is locally obvious. This general idea could be extended to the scalar case as well.

If we have a caller that knows a particular argument can never be null, we can exploit this fact while simplifying values in the inline cost analysis. This has the effect of reducing the cost for inlining when a null check is present in the callee, but the value is known non null in the caller. In particular, any dependent control flow can be discounted from the cost estimate.

[LAA] Try to prove non-wrapping of pointers if SCEV cannot

Summary:
Scalar evolution does not propagate the non-wrapping flags to values
that are derived from a non-wrapping induction variable because
the non-wrapping property could be flow-sensitive.

This change is a first attempt to establish the non-wrapping property in
some simple cases.  The main idea is to look through the operations
defining the pointer.  As long as we arrive to a non-wrapping AddRec via
a small chain of non-wrapping instruction, the pointer should not wrap
either.

I believe that this essentially is what Andy described in

MIR Serialization: Serialize machine basic block operands.

This commit serializes machine basic block operands. The
machine basic block operands use the following syntax:

  %bb.<id>[.<name>]

This commit also modifies the YAML representation for the
machine basic blocks - a new, required field 'id' is added
to the MBB YAML mapping.

The id is used to resolve the MBB references to the
actual MBBs. And while the name of the MBB can be
included in a MBB reference, this name isn't used to
resolve MBB references - as it's possible that multiple
MBBs will reference the same BB and thus they will have the
same name. If the name is specified, the parser will verify
that it is equal to the name of the MBB with the specified id.

coverage instrumentation.
