Summary:
Delete the BasicBlockPass and BasicBlockManager, all its dependencies and update documentation.
The BasicBlockManager was improperly tested and found to be potentially broken, and was deprecated as of rL373254.
In light of the switch to the new pass manager coming before the next release, this patch is a first cleanup of the LegacyPassManager.

Add a new reducer that drops metadata that does not contribute to the
crash from instructions.
It adjusts the metadata.ll test case, as now also the instruction level
metadata will get dropped.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
This function is very similar to add_llvm_library(), so this patch merges it
into add_llvm_library() and replaces all calls to add_llvm_loadable_module(lib ...)
with add_llvm_library(lib MODULE ...)

Summary:
In addition to reducing the functions in an LLVM module, bugpoint now
reduces the function attributes associated with each of the remaining
functions.
To test this, add a -bugpoint-crashfuncattr test pass, which crashes if
a function in the module has a "bugpoint-crash" attribute. A test case
demonstrates that the IR is reduced to just that one attribute.

TestPasses.cpp has the following include chain:
llvm/IR/InstVisitor.h
llvm/IR/CallSite.h
llvm/IR/Attributes.h
llvm/IR/Attributes.gen
This means bugpoint-passes needs to depend on intrinsics_gen.

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 patch adds two flags to `bugpoint`: "-replace-funcs-with-null" and "-disable-pass-list-reduction".
When "-replace-funcs-with-null" is specified, bugpoint will, instead of simply deleting function bodies, replace all uses of functions and then will delete functions completely from the test module, correctly handling aliasing and @llvm.used && @llvm.compiler.used. This part was conceived while trying to debug the PNaCl IR simplification passes, which don't allow undefined functions (ie no declarations).
With "-disable-pass-list-reduction", bugpoint won't try to reduce the set of passes causing the "crash". This is needed in cases where one is trying to debug an issue inside the PNaCl IR simplification passes which is causing an PNaCl ABI verification error, for example.

it handles export files in a strange way: It generates a .exports file from a

into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.
There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.
The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.
I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).
I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

Support land.
This is in preparation to start working to expand InstVisitor into more
special-purpose visitors that are still generic and can be re-used
across different passes. The expansion will go into the Analylis tree
though as nothing in VMCore needs it.
