Keith Walker ea9483f847 [DWARF] Add CIE header fields address_size and segment_size when generating dwarf-4
The DWARF-4 specification added 2 new fields in the CIE header called
address_size and segment_size.
Create these 2 new fields when generating dwarf-4 CIE entries, print out
the new fields when dumping the CIE and update tests

Frederic Riss ac10b0d61d Try to appease buildbots.
It seems ArrayRefs to multi-dimensional arrays confuse some compilers.

Frederic Riss c0dd7243ee [dwarfdump] Make debug_frame dump actually useful.
This adds support for pretty-printing instruction operands. The new
output looks like:

00000000 00000010 ffffffff CIE

Frederic Riss 2fe0e54fd6 [dwarfdump] Don't print meaningless pointer.
CIE pointers were never filled in before, and printing the pointer
is totally pointless anyway.

Frederic Riss 056ad058bb DWARFDebugFrame: Move some code around. NFC.
Move the FrameEntry::dumpInstructions down in the file at some
place where it can see the declarations of FDE and CIE.

Frederic Riss baf195f7eb DWARFDebugFrame: Actually collect CIEs associated with FDEs.
This is the first commit in a small series aiming at making
debug_frame dump more useful (right now it prints a list of
opeartions without their operands).

Zachary Turner 82af9438d0 Move DebugInfo to DebugInfo/DWARF.
In preparation for adding PDB support to LLVM, this moves the
DWARF parsing code to its own subdirectory under DebugInfo, and
renames LLVMDebugInfo to LLVMDebugInfoDWARF.

This is purely a mechanical / build system change.
