b6714227ed Move the string pools down into the units. No functional change.

dd8e9f395e Add support for separating strings for the split debug info DWARF5
proposal. This leaves the strings in the skeleton die as strp,
but in all dwo files they're accessed now via DW_FORM_GNU_str_index.

Add support for dumping these sections and modify the fission-cu.ll
testcase to have the correct strings and form. Fix a small bug
in the fixed form sizes routine that involved out of array accesses
for the table and add a FIXME in the extractFast routine to fix
this up.

0e3e9b79f6 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.

a1514e24cc 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. =]

7b451cf356 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.

0bcbd1df7a 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.
