[AArch64] Changes some SchedAlias to WriteRes for Cortex-A57.
Using SchedAliases is convenient and works well for latency and resource

AArch64WriteLatencyTable with a WriteResourceID of 0, breaking any
SchedReadAdvance since the lookup will fail.

Divergence analysis for GPU programs
Summary:
Some optimizations such as jump threading and loop unswitching can negatively
affect performance when applied to divergent branches. The divergence analysis
added in this patch conservatively estimates which branches in a GPU program
can diverge. This information can then help LLVM to run certain optimizations
selectively.

[DAGCombine] Fix a bug in MergeConsecutiveStores.
The bug manifests when there are two loads and two stores chained as follows in
a DAG,
(ld v3f32) -> (st f32) -> (ld v3f32) -> (st f32)
and the stores' values are extracted from the preceding vector loads.
MergeConsecutiveStores would replace the first store in the chain with the
merged vector store, which would create a cycle between the merged store node
and the last load node that appears in the chain.
This commits fixes the bug by replacing the last store in the chain instead.

Go bindings: make various DIBuilder arguments optional.
r234262 changed some code in DIBuilderBindings.cpp to use the unwrap function
to unwrap debug metadata. The problem with this is that unwrap asserts that
its argument is non-null, which is not what we want in a number of places
in DIBuilder where the argument is optional. This change makes certain
arguments optional by adding null checks in places where it is required,
fixing the llgo build.

[LoopAccesses] Allow analysis to complete in the presence of uniform stores
(Re-apply r234361 with a fix and a testcase for PR23157)
Both run-time pointer checking and the dependence analysis are capable
of dealing with uniform addresses. I.e. it's really just an orthogonal
property of the loop that the analysis computes.
Run-time pointer checking will only try to reason about SCEVAddRec
pointers or else gives up. If the uniform pointer turns out the be a
SCEVAddRec in an outer loop, the run-time checks generated will be
correct (start and end bounds would be equal).
In case of the dependence analysis, we work again with SCEVs. When
compared against a loop-dependent address of the same underlying object,
the difference of the two SCEVs won't be constant. This will result in
returning an Unknown dependence for the pair.
When compared against another uniform access, the difference would be
constant and we should return the right type of dependence
(forward/backward/etc).
The changes also adds support to query this property of the loop and
modify the vectorizer to use this.

Summary:
Even though there is no 2nd register operand in the "lw/sw $8, symbol" case, we still try to find one,

We can avoid this by checking if the 2nd register operand is different from $0, before generating the addu.

Revert "Try a third time to fix MSVC build after r234290"
This reverts commit r234295 (and r234294 and r234292 before it). I
removed the implicit conversion to `MDTuple*` r234326, so there's no
longer an ambiguity in `operator[]()`.
I think MSVC should accept the original code now...

AArch64: Don't lower ISD::SELECT to ISD::SELECT_CC
Instead of lowering SELECT to SELECT_CC which is further lowered later
immediately call the SELECT_CC lowering code. This is preferable
because:
- Avoids an unnecessary roundtrip through the legalization queues with
an intermediate node.
- More importantly: Lowered operations get visited last leading to SELECT_CC
getting visited with legalized operands and unlegalized ones for preexisting
SELECT_CC nodes. This does not hurt the current code (hence no testcase) but
is required for another patch I am working on.
