Summary:
The reason for it is limit of detecting ncurses on various systems. For
example, Ubuntu ships with <curses.h> and linkage from <ncurses.h>, <ncurses.h>
isn't detected by CMake. Detecting `<curses.h>` on NetBSD is reusing
conflicting header from the host curses(8) and pkgsrc's ncurses library.
ncurses ships on most (till conflicting) systems with curses.h. On NetBSD it
might be conflicting, so the ncurses headers are installed with pkgsrc to a
subdirectory "ncurses/".
Patch by Kamil Rytarowski. Thanks!

Windows EH funclets need to always return to a single parent funclet. However, it is possible for earlier optimizations to combine funclets (probably based on one funclet having an unreachable terminator) in such a way that this condition is violated.
These changes add code to the WinEHPrepare pass to detect situations where a funclet has multiple parents and clone such funclets, fixing up the unwind and catch return edges so that each copy of the funclet returns to the correct parent funclet.

Summary:
We frequently run bugpoint on a linked module that consists of all
modules we create while jitting the julia standard library. This module
has a very large number of compile units (10000+) in `llvm.dbg.cu`,
which didn't get reduced at all, requiring manual post processing.
This is an attempt to have bugpoint go through and attempt to reduce
the number of global named metadata nodes as well as their operands,
to cut down the number of roots for such metadata.

Summary:
This does a broad first pass on cleaning up a lot of the noise when
using pylint on these scripts. It mostly addresses issues of:
* Mixed tabs and spaces.
* Trailing whitespace.
* Semicolons where they aren't needed.
* Incorrect whitespace around () and [].
* Superfluous parentheses.
There will be subsequent patches with further changes that build
upon these.

The bug: I missed adding break statements in the switch / case.
Original commit message:
[SCEV] Teach SCEV some axioms about non-wrapping arithmetic
Summary:
- A s< (A + C)<nsw> if C > 0
- A s<= (A + C)<nsw> if C >= 0
- (A + C)<nsw> s< A if C < 0
- (A + C)<nsw> s<= A if C <= 0
Right now `C` needs to be a constant, but we can later generalize it to
be a non-constant if needed.

Summary: This fixes a bug that's easily encountered in LLDB
(https://llvm.org/bugs/show_bug.cgi?id=22875). The problem here is that we
mangle a name during debug info emission, but never actually emit the actual
Decl, so we run into problems in EmitDeclMetadata (which assumes such a Decl
exists). Fix that by just skipping metadata emissions for mangled names that
don't have associated Decls.

Previously, subprograms contained a metadata reference to the function they
described. Because most clients need to get or set a subprogram for a given
function rather than the other way around, this created unneeded inefficiency.
For example, many passes needed to call the function llvm::makeSubprogramMap()
to build a mapping from functions to subprograms, and the IR linker needed to
fix up function references in a way that caused quadratic complexity in the IR
linking phase of LTO.
This change reverses the direction of the edge by storing the subprogram as
function-level metadata and removing DISubprogram's function field.
Since this is an IR change, a bitcode upgrade has been provided.
Fixes PR23367. An upgrade script for textual IR for out-of-tree clients is
attached to the PR.

for the root cause. The 'using llvm::isa;' declaration in Basic/LLVM.h only
pulls the declarations of llvm::isa that were declared prior to it into
namespace clang. In a modules build, this is a hermetic set of just the
declarations from LLVM. In a non-modules build, we happened to also pull the
declaration from lib/CodeGen/Address.h into namespace clang, which made the
code in question accidentally compile.

We already had a test for this for 32-bit SEH catchpads, but those don't
actually create funclets. We had a bug that only appeared in funclet
prologues, where we would establish EBP and ESI as our FP and BP, and
then downstream prologue code would overwrite them.
While I was at it, I fixed Win64+funclets+stackrealign. This issue
doesn't come up as often there due to the ABI requring 16 byte stack
alignment, but now we can rest easy that AVX and WinEH will work well
together =P.

Mangling type information into MachineInstr opcode names was a temporary
measure, and it's starting to get hairy. At the same time, the MC instruction
printer wants to use AsmString strings for printing. This patch takes the
first step, starting the process of adding AsmStrings for instructions.
