c7c5395326 unittests/Support/DataExtractorTest.cpp: Specify ULL explicitly to a few constants. 
It seems i686-cygwin-gcc-4.3 does not accept 64-bit constant without LL.

e585e8ee86 Distinguish complex mapped values from forced recomputation. 
When a ParentVNI maps to multiple defs in a new interval, its live range
may still be derived directly from RegAssign by transferValues().

On the other hand, when instructions have been rematerialized or
hoisted, it may be necessary to completely recompute live ranges using
LiveRangeCalc::extend() to all uses.

Use a bit in the value map to indicate that a live range must be
recomputed.  Rename markComplexMapped() to forceRecompute().

This fixes some live range verification errors when
-split-spill-mode=size hoists back-copies by recomputing source ranges
when RegAssign kills can't be moved.

32fad58636 Implement -split-spill-mode=size. 
Whenever the complement interval is defined by multiple copies of the
same value, hoist those back-copies to the nearest common dominator.

This ensures that at most one copy is inserted per value in the
complement inteval, and no phi-defs are needed.

c4e7a56915 Sketch out a DWARF parser. 
This introduces a new library to LLVM: libDebugInfo. It will provide debug information
parsing to LLVM. Much of the design and some of the code is taken from the LLDB project.

It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an
object file. It can be used to write tests for DWARF input and output easily.

fcc23eeec7 Add the DataExtractor utility class. 
It is an endian-aware helper that can read data from a StringRef. It will
come in handy for DWARF parsing. This class is inspired by LLDB's
DataExtractor, but is stripped down to the bare minimum needed for DWARF.

Comes with unit tests!

c0aa77ec15 Use a separate LiveRangeCalc for the complement in spill modes. 
The complement interval may overlap the other intervals created, so use
a separate LiveRangeCalc instance to compute its live range.

A LiveRangeCalc instance can only be shared among non-overlapping
intervals.
