The `GNUABIN32` environment in a target triple implies using the N32
ABI. This patch adds support for this environment and switches on N32
ABI if necessary.

The new name is a better fit: This class does not actually spawn any new
threads for compilation, it is just safe to call from multiple threads
concurrently.
The "Simple" part of the name did not convey much either, so it was
dropped.

r344558 added an assignment to a TerminatorInst* from
BasicBlock::getTerminatorInst(), but BasicBlock::getTerminatorInst() returns an
Instruction* rather than a TerminatorInst* since r344504 so this fails to
compile.
Changing the variable to an Instruction* should get the bots building again.

Make the code of blockEndsInUnreachable to match the function
blockEndsInUnreachable in CodeGen/BranchFolding.cpp. I also have
added a note to make sure the code of this function will not be
modified unless the back-end version is also modified.
An early return before outlining has been added to avoid
outlining the full function body when the first block in the
function is marked cold.
The static analysis of cold code has been amended to avoid
marking the whole function as cold by back-propagation
because the back-propagation would mark blocks with return
statements as cold.
The patch adds debug statements to help discover these problems.

There are several places where we use CMAKE_CONFIGURATION_TYPES to determine if we are using an IDE generator and in turn decide not to generate some of the convenience targets (like all the install-* and check-llvm-* targets). This decision is made because IDEs don't always deal well with the thousands of targets LLVM can generate.
This approach does not work for Visual Studio 15's new CMake integration. Because VS15 uses a Ninja generator, it isn't a multi-configuration build, and generating all these extra targets mucks up the UI and adds little value.
With this change we still don't generate these targets by default for Visual Studio and Xcode generators, and LLVM_ENABLE_IDE becomes a switch that can be enabled on the VS15 CMake builds, to improve the IDE experience.
This is a re-land of r340435, with a few minor fix-ups. The issues causing the revert were addressed in r344218, r344219, and r344553.

AARCH64 equivalent to D53257 - uses widening pairwise adds on vXi8 CTPOP to support i16/i32/i64 vectors.
This is a blocker for generic vector CTPOP expansion (P32655) - this will remove the aarch64 diff from D53258.

There really aren't any generator behaviors that we need to take `CMAKE_EXTRA_GENERATOR` into account for. Where we need to take different behaviors for IDEs is mostly in enabling or disabling certain build system features that are optional but trip up the IDE UIs. Like the generation of lots of utility targets.
By changing the LLVM_ENABLE_IDE default to only being on for multi-configuration generators, we allow gating where it will impact the UI presentation, while also supporting optionally disabling the generation if your tooling workflow encounters problems. Presently being able to manually disable extra target generation is useful for Visual Studio 2017's CMake integration where the IDE has trouble displaying and working with the large number of optional targets.

Summary:
If the names are not unique, the tests overwrite each other's results and logs. This also causes failures on platforms where the files are locked for writing.
The names of the class/test pairs *have to* always be unique. The easiest way to achieve that is to name each class differently (usually the same as the file name).

Variable updates within the outlined function are invisible to
debuggers. This could be improved by defining a DISubprogram for the
new function. For the moment, simply erase the debug intrinsics instead.
This fixes verifier failures about function-local metadata being used in
the wrong function, seen while testing the hot/cold splitting pass.

This support is slightly different then the X86_64 implementation in that calls
to __morestack don't need to get rewritten to calls to __moresatck_non_split
when a split-stack caller calls a non-split-stack callee. Instead the size of
the stack frame requested by the caller is adjusted prior to the call to
__morestack. The size the stack-frame will be adjusted by is tune-able through a
new --split-stack-adjust-size option.

This is intended to make the backend on par with functionality that was
added to the IR version of SimplifyDemandedVectorElts in:
rL343727
...and the original motivation is that we need to improve demanded-vector-elements
in several ways to avoid problems that would be exposed in D51553.

In C++17, when class C has large alignment value, a special case of
overload resolution rule kicks in for expression new C that causes the aligned
version of operator new() to be called. The aligned new has two arguments:
size and alignment. However, the new-expression has only one "argument":
the construct-expression for C(). This causes a false positive in
core.CallAndMessage's check for matching number of arguments and number
of parameters.
Update CXXAllocatorCall, which is a CallEvent sub-class for operator new calls
within new-expressions, so that the number of arguments always matched
the number of parameters.

We don't need a separate node for every symbol, because whenever the first
symbol leaks, a bug is emitted, the analysis is sinked, and the checker
callback immediately returns due to State variable turning into null,
so we never get to see the second leaking symbol.
Additionally, we are no longer able to break normal analysis while experimenting
with debug dumps.

This patch is a part of https://reviews.llvm.org/D48456 in an attempt to
split them up. This contains the code for casting between fixed point types
and other fixed point types.
The method for converting between fixed point types is based off the convert()
method in APFixedPoint.
