07c3167c2b [DWARF parser] DWARFDebugFrame: Make FrameEntry struct smaller.
FrameEntry doesn't need to hold a reference to the section it is
located in. Instead, pass DataExtractor as an argument of parsing
function.

No functionality change.

0b6cb7104b [C++11] More 'nullptr' conversion. In some cases just using a boolean check instead of comparing to nullptr.

974a445bd9 Re-sort all of the includes with ./utils/sort_includes.py so that
subsequent changes are easier to review. About to fix some layering
issues, and wanted to separate out the necessary churn.

Also comment and sink the include of "Windows.h" in three .inc files to
match the usage in Memory.inc.

46e0d1d58c Code cleanup: pass Offset by pointer to parseInstruction to more explicitly
convey that it's a INOUT argument.
Also, if parsing of entry instructions fails, don't push the entry.

7bf3d6a043 Previously, parsing capability of the .debug_frame section was added
to lib/DebugInfo, with dumping in llvm-dwarfdump. This patch adds
initial ability to parse and dump CFA instructions contained in
entries.

To keep it manageable, the patch omits some more advanced capabilities
(accounted in TODOs):

* Parsing of instructions with BLOCK arguments (expression lists)
* Dumping of actual instruction arguments (currently only names are
dumped). This is quite tricky since the dumper has to effectively
"interpret" the instructions.

0b821eff4c The patch to fix some issues in r174543 fixed the lines failing the test, but missed a couple
of lines which weren't being explicitly looked at and were printing incorrect results. These
values clearly must lie within 32 bits, so the casts are definitely safe.

b2ac7c09b1 Failing builds because a private class member is not being used after
initialization is one of the reasons I consider -werror to be shoddy.
