b52cdda782 clang-format these lines to fix Visual C++ warning.
Visual C++ 2013 complains "warning C4138: '*/' found outside of comment"
about the code

 CallInst */*CI*/

but compiles OK. clang-formatting these lines adds an extra space and
makes Visual C++ satisfied.

bf2e6a6be2 Change test to accept an additional critical edge split.
The two hot blocks are right next to each other and I verified that
there is no performance regression by compressing/uncompressing some
files with a minigzip built with the different options.

0328ca6cd7 [ARM] Align stack objects passed to memory intrinsics
Memcpy, and other memory intrinsics, typically tries to use LDM/STM if
the source and target addresses are 4-byte aligned. In CodeGenPrepare
look for calls to memory intrinsics and, if the object is on the
stack, 4-byte align it if it's large enough that we expect that memcpy
would want to use LDM/STM to copy it.

703b185464 Remove many superfluous SmallString::str() calls.
Now that SmallString is a first-class citizen, most SmallString::str()
calls are not required. This patch removes a whole bunch of them, yet
there are lots more.

There are two use cases where str() is really needed:
1) To use one of StringRef member functions which is not available in
SmallString.
2) To convert to std::string, as StringRef implicitly converts while 
SmallString do not. We may wish to change this, but it may introduce
ambiguity.

e027d74733 [SCEV] Make isImpliedCond smarter.
Summary:
This change teaches isImpliedCond to infer things like "X sgt 0" => "X -
1 sgt -1".  The `ConstantRange` class has the logic to do the heavy
lifting, this change simply gets ScalarEvolution to exploit that when
reasonable.

da5f3a3ca5 [ConstantRange] Split makeICmpRegion in two.
Summary:
This change splits `makeICmpRegion` into `makeAllowedICmpRegion` and
`makeSatisfyingICmpRegion` with slightly different contracts.  The first
one is useful for determining what values some expression //may// take,
given that a certain `icmp` evaluates to true.  The second one is useful
for determining what values are guaranteed to //satisfy// a given
`icmp`.

AFAICT, there's no real functionality change here.  The tag was

b415e6b2f2 Centralize the handling of unique ids for temporary labels.
Before this patch code wanting to create temporary labels for a given entity
(function, cu, exception range, etc) had to keep its own counter to have stable
symbol names.

createTempSymbol would still add a suffix to make sure a new symbol was always
returned, but it kept a single counter. Because of that, if we were to use
just createTempSymbol("cu_begin"), the label could change from cu_begin42 to
cu_begin43 because some other code started using temporary labels.

Simplify this by just keeping one counter per prefix and removing the various
specialized counters.

3a660c933a Add assertion to detect invalid registers in the PowerPC MC instruction lowering.
We have observed that noreg was being generated due to a bug in FastIsel and was not being detected during emission. It happens that in the Asm emission there is an assertion that detects this in getRegisterName() from the tbl-generated file PPCGenAsmWriter.inc. However, when emitting an Obj file, invalid registers can be emitted given that no check are made in getBinaryCodeFromInstr() from PPCGenMCCodeEmitter.inc. In order to cover all cases this adds an assertion for reg operands in LowerPPCMachineInstrToMCInst.

25e7243eda Fix GCC -Wparentheses warning (& reformat now that the precedence is fixed)
Benign warning (clang deliberately suppresses this case) but does
regularly produce bad formatting, so it's nice to fix/reformat.

2f5bc29926 Verifier: Set --verify-debug-info=true by default
r186634 started verifying debug info, and r194986 disabled it by default
because it was too expensive to run the checks on every function (since
most of the graph was reachable from each function).

r206300 moved the checks to module-level to make it cheaper, but there
was already quite a bit of testcase bitrot (and the verifier would only
print `<badref>`) so I guess no one had time to turn it back on.

This does just that.  Upgrade scripts this past autumn and winter
probably fixed some of the bitrot, and this weekend I fixed the verifier
output (r232275, r232417, r232418) and thusly the remaining failing
testcases (r232290, r232415).

This is part of PR22777.
