bd75475bfc DebugInfo: Remove dead code, DICompositeType::addMember(DIDescriptor D)
It's no longer necessary to lazily add members to the DICompositeType
member list. Instead any lazy members (special member functions and
member template instantiations) are added to the parent late based on
their context link, the same way that nested types have always been
handled (never being in the member list - just added to the parent DIE
lazily based on context).

Clang's been updated not to use this function anymore as it improves
type unit consistency by never emitting lazy members in type units.

1739b6cc20 Use two variables here rather than reusing (and abusing) one. This is
much more clear to me. I meant to make this change before committing the
original patch, but forgot to merge it in. Sorry.

5ff21b4111 Introduce a simple line-by-line iterator type into the Support library.
This is an iterator which you can build around a MemoryBuffer. It will
iterate through the non-empty, non-comment lines of the buffer as
a forward iterator. It should be small and reasonably fast (although it
could be made much faster if anyone cares, I don't really...).

This will be used to more simply support the text-based sample
profile file format, and is largely based on the original patch by
Diego. I've re-worked the style of it and separated it from the work of
producing a MemoryBuffer from a file which both simplifies the interface
and makes it easier to test.

The style of the API follows the C++ standard naming conventions to fit
in better with iterators in general, much like the Path and FileSystem
interfaces follow standard-based naming conventions.

c7b0b7dc8f Add support to indvars for optimizing sadd.with.overflow.
Split sadd.with.overflow into add + sadd.with.overflow to allow
analysis and optimization. This should ideally be done after
InstCombine, which can perform code motion (eventually indvars should
run after all canonical instcombines). We want ISEL to recombine the
add and the check, at least on x86.

This is currently under an option for reducing live induction
variables: -liv-reduce. The next step is reducing liveness of IVs that
are live out of the overflow check paths. Once the related
optimizations are fully developed, reviewed and tested, I do expect
this to become default.

Now the instrumented code looks like:

4ef09de13e The count() function for STL datatypes returns unsigned, even

Some of the LLVM ADT already return unsigned count(), while
others return bool count().

This patch modifies SmallPtrSet, SmallSet, SparseSet count()
to return unsigned instead of bool:

 1 instead of true
 0 instead of false

More ADT to follow.
