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.

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!

more strict about the alignment checking. This was found by inspection
and I don't have any testcases so far, although the llvm testsuite runs
without any problem.

This function is used to flag values where the complement interval may
overlap other intervals.  Call it from overlapIntv, and use the flag to
fully recompute those live ranges in transferValues().

Teach the Thumb ASM parser that BKPT is allowed in IT blocks, even though it is always executed unconditionally.

Three out of four clients prefer this interface which is consistent with
extendIntervalEndTo() and LiveRangeCalc::extend().

llvm-svn: 139604

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.

Only disassembler instructions with vvvv != 1111 if the instruction actually uses the vvvv field to encode an operand. Fixes PR10851.

Remove filter that was preventing MOVDQU/MOVDQA and their VEX forms from being disassembled. Also added encodings for the other register/register form of these instructions. Fixes PR10848.

Fix encoding of VMOVDQU to not simultaneously be 'TB OpSize' and 'XS'. 'XS' is correct and seems to have been taking priority.
