d3557eb1f8 Editorial changes in the programmers manual.
VMCore was renamed to IR back in 2013. The relevant "core"
implementations were moved into the lib/IR directory at the same time.

784545fba0 [ADT][CMake][AutoConf] Fail-fast iterators for DenseMap
Summary:
This patch is an attempt at making `DenseMapIterator`s "fail-fast".
Fail-fast iterators that have been invalidated due to insertion into
the host `DenseMap` deterministically trip an assert (in debug mode)
on access, instead of non-deterministically hitting memory corruption
issues.

Enabling fail-fast iterators breaks the LLVM C++ ABI, so they are
predicated on `LLVM_ENABLE_ABI_BREAKING_CHECKS`.
`LLVM_ENABLE_ABI_BREAKING_CHECKS` by default flips with
`LLVM_ENABLE_ASSERTS`, but can be clamped to ON or OFF using the CMake /
autoconf build system.

dde94fb301 Introduce a section to the programmers manual about type hierarchies,
polymorphism, and virtual dispatch.

This is essentially trying to explain the emerging design techniques
being used in LLVM these days somewhere more accessible than the
comments on a particular piece of infrastructure. It covers the
"concepts-based polymorphism" that caused some confusion during initial
reviews of the new pass manager as well as the tagged-dispatch mechanism
used pervasively in LLVM and Clang.

Perhaps most notably, I've tried to provide some criteria to help
developers choose between these options when designing new pieces of
infrastructure.

d9ebc5991b ADT: Fix MapVector::erase()
Actually update the changed indexes in the map portion of `MapVector`
when erasing from the middle.  Add a unit test that checks for this.

Note that `MapVector::erase()` is a linear time operation (it was and
still is).  I'll commit a new method in a moment called
`MapVector::remove_if()` that deletes multiple entries in linear time,
which should be slightly less painful.

761f33167f Kill the LLVM global lock.
This patch removes the LLVM global lock, and updates all existing
users of the global lock to use their own mutex.    None of the
existing users of the global lock were protecting code that was
mutually exclusive with any of the other users of the global
lock, so its purpose was not being met.

04de60e28f GraphWriter: detect graph viewer programs at runtime
Replace the crufty build-time configure checks for program paths with
equivalent runtime logic.

This lets users install graphing tools as needed without having to reconfigure
and rebuild LLVM, while eliminating a long chain of inappropriate compile
dependencies that included GUI programs and the windowing system.

Additional features:

 * Support the OS X 'open' command to view graphs generated by any of the
   Graphviz utilities. This is an alternative to the Graphviz OS X UI which is
   no longer available on Mountain Lion.

 * Produce informative log output upon failure to indicate which programs can
   be installed to view graphs.

Ping me if this doesn't work for your particular environment.

7225e27b4c [Modules] Move ValueMap to the IR library. While this class does not
directly care about the Value class (it is templated so that the key can
be any arbitrary Value subclass), it is in fact concretely tied to the
Value class through the ValueHandle's CallbackVH interface which relies
on the key type being some Value subclass to establish the value handle
chain.

Ironically, the unittest is already in the right library.

4991289b33 [docs] The STL "binary search" has a non-obvious name.
std::lower_bound is the canonical "binary search" in the STL
(std::binary_search generally is not what you want). The name actually
makes a lot of sense (and also has a beautiful symmetry with the
std::upper_bound algorithm). The name is nonetheless non-obvious.

Also, remove mention of "radix search". It's not even clear how that
would work in the context of a sorted vector. AFAIK "radix search" only
makes sense when you have a trie-like data structure.
