Rename getMaximumUnrollFactor -> getMaxInterleaveFactor; also rename option names controlling this variable.

"Unroll" is not the appropriate name for this variable. Clang already uses 
the term "interleave" in pragmas and metadata for this.

Make CallingConv::ID an alias of "unsigned".

Summary:
Make CallingConv::ID a plain unsigned instead of enum with a
fixed set of valus. LLVM IR allows arbitraty calling conventions (you are
free to write cc12345), and loading them as enum is an undefined
behavior. This was reported by UBSan.

[AArch64] Revert r216141 for cyclone

The increase of the interleave factor to 4 has side-effects
like performance losses eg. due to reminder loops being executed
more frequently and may increase code size. It requires more
analysis and careful heuristic tuning. Expect double digit gains
in small benchmarks like lowercase.c and losses in puzzle.c.

[AlignmentFromAssumptions] Don't divide by zero for unknown starting alignment

The routine that determines an alignment given some SCEV returns zero if the
answer is unknown. In a case where we could determine the increment of an
AddRec but not the starting alignment, we would compute the integer modulus by
zero (which is illegal and traps). Prevent this by returning early if either
the start or increment alignment is unknown (zero).

Add doInitialization/doFinalization to DataLayoutPass.

With this a DataLayoutPass can be reused for multiple modules.

Once we have doInitialization/doFinalization, it doesn't seem necessary to pass
a Module to the constructor.

Overall this change seems in line with the idea of making DataLayout a required
part of Module. With it the only way of having a DataLayout used is to add it
to the Module.

R600/SI: Report offset in correct units for st64 DS instructions

Need to convert the 64 element offset into bytes, not just the element
size like the normal case instructions.

Noticed by inspection. This can't be hit now because
st64 instructions aren't emitted during instruction selection,
and the post-RA scheduler isn't enabled.

shared_ptrify ownershp of PoolEntries in PBQP's CostPool

Leveraging both intrusive shared_ptr-ing (std::enable_shared_from_this)
and shared_ptr<T>-owning-U (to allow external users to hold
std::shared_ptr<CostT> while keeping the underlying PoolEntry alive).

The intrusiveness could be removed if we had a weak_set that implicitly
removed items from the set when their underlying data went away.

This /might/ fix an existing memory leak reported by LeakSanitizer in
r217504.
