3bf29fda91 For the dwarf5 split debug info code split out the string section 
per compile unit/skeleton compile unit. Update tests accordingly.

2943ce80f3 Declare class DwarfDebug before use instead of relying on a forward declaration 
from some other unrelated header.

c8a310edc1 Refactor out the abbreviation handling into a separate class that 
controls each of the abbreviation sets (only a single one at the
moment) and computes offsets separately as well for each set
of DIEs.

No real function change, ordering of abbreviations for the skeleton
CU changed but only because we're computing in a separate order. Fix
the testcase not to care.

cdf218d606 Use the somewhat semantic term "split dwarf" it more matches what's 
going on and makes a lot of the terminology in comments make more sense.

802d755533 Sort includes for all of the .h files under the 'lib' tree. These were 
missed in the first pass because the script didn't yet handle include
guards.

Note that the script is now able to handle all of these headers without
manual edits. =]

9c2ecd93d0 Add some first skeleton work for the DWARF5 Fission proposal. Emit 
part of the compile unit CU and start separating out information into
the various sections that will be pulled out later.

c1c8a1bb6a Have the DbgVariable "isArtificial" and "isObjectPointer" not 
care about it being an argument variable so that we can decide
that captured block and lambda vars that don't happen to
be arguments could be an argument pointer.

Add the object pointer for one case onto the subprogram die.

e38859dc8e Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp and 
include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h.

The reasoning is because the DebugInfo module is simply an interface to the
debug info MDNodes and has nothing to do with analysis.
