1. Used update_llc_test_checks.py to tighten checks
2. Fixed triple (nothing Darwin-specific here)
3. Replaced CPU specifiers with attributes
4. Fixed comments
5. Removed IvyBridge run because it did not add any coverage

My commit r239790 which introduced serialization for simple machine function attributes didn't
initialize them when parsing because I have misread the documentation for YAML IO's mapOptional
method. The mapOptional method doesn't actually set the values to the values returned by the
default constructor for that type when the key value pair is missing, it just doesn't modify
those values, so they still contain the value that was set during initialization by the default
constructor. But the fields in yaml::MachineFunction with types like unsigned and bool are not
initialized by default, and thus they can still be uninitialized after mapOptional during parsing.
This commit adds default initialization for those fields to prevent this.

Deduplicates some code and lets us use LEA on atom when adjusting the

While the hash functions are subtly different it shouldn't have an
impact. Instructions are checked with isIdenticalTo later.

Summary:
Currently intrinsics don't affect the creation of the call graph.
This is not accurate with respect to statepoint and patchpoint
intrinsics -- these do call (or invoke) LLVM level functions.
This change fixes this inconsistency by adding a call to the external
node for call sites that call these non-leaf intrinsics. This coupled
with the fact that these intrinsics also escape the function pointer
they call gives us a conservatively correct call graph.

They had been getting emitted as a section + offset reference, which
is bogus since the value needs to be the offset within the GOT, not
the actual address of the symbol's object.

any tests and I even don't know how to run the tests. This seems like a
minimal change to make them work again, although I can't really verify
at this point. Additionally, it probably makes sense to propagate the
personality parameter removal further.

- zext the value to alloc size first, then check if the value repeats
with zero padding included. If so we can still emit a .space
- Do the checking with APInt.isSplat(8), which handles non-pow2 types
- Also handle large constants (bit width > 64)
- In a ConstantArray all elements have the same type, so it's sufficient
to check the first constant recursively and then just compare if all
following constants are the same by pointer compare

This commit ensures that a value that's passed into YAML's IO mapOptional method
is going to be assigned a value returned by the default constructor for that
value's type when the appropriate key is not present in the YAML mapping.

Summary:
This is done by first adding two additional instructions to convert the
alloca returned address to local and convert it back to generic. Then
replace all uses of alloca instruction with the converted generic
address. Then we can rely NVPTXFavorNonGenericAddrSpace pass to combine
the generic addresscast and the corresponding Load, Store, Bitcast, GEP
Instruction together.

MCFragment didn't really need vtables. The majority of virtual methods were just getters and setters.
This removes the vtables and uses dispatch on the kind to do things like delete which needs to
get the appropriate class.
This reduces memory on the verify use list order test case by about 2MB out of 800MB.

There is a one-to-one relationship between X86Subtarget and
X86FrameLowering, but every frame lowering method would previously pull
the subtarget off the MachineFunction and query some subtarget
properties.
Over time, these locals began to grow in complexity and it became
important to keep their names and meaning in sync across all of the
frame lowering methods, leading to duplication. We can eliminate that
duplication by computing them once in the constructor.

The personality routine currently lives in the LandingPadInst.
This isn't desirable because:
- All LandingPadInsts in the same function must have the same
personality routine. This means that each LandingPadInst beyond the
first has an operand which produces no additional information.
- There is ongoing work to introduce EH IR constructs other than
LandingPadInst. Moving the personality routine off of any one
particular Instruction and onto the parent function seems a lot better
than have N different places a personality function can sneak onto an
exceptional function.

It's been used before to avoid infinite loops caused by separate CGP
optimizations undoing one another. We found one more such issue
caused by r238054. To avoid it, generalize the "InsertedTruncs"
set to any inst, and use it to avoid touching those again.
