the pubnames and pubtypes tables. LLDB can currently use this format
and a full spec is forthcoming and submission for standardization is planned.

A basic summary:

The dwarf accelerator tables are an indirect hash table optimized
for null lookup rather than access to known data. They are output into
an on-disk format that looks like this:

.-------------.
|  HEADER     |
|-------------|
|  BUCKETS    |
|-------------|
|  HASHES     |
|-------------|
|  OFFSETS    |
|-------------|
|  DATA       |
`-------------'

where the header contains a magic number, version, type of hash function,
the number of buckets, total number of hashes, and room for a special
struct of data and the length of that struct.

The buckets contain an index (e.g. 6) into the hashes array. The hashes
section contains all of the 32-bit hash values in contiguous memory, and
the offsets contain the offset into the data area for the particular
hash.

For a lookup example, we could hash a function name and take it modulo the
number of buckets giving us our bucket. From there we take the bucket value
as an index into the hashes table and look at each successive hash as long
as the hash value is still the same modulo result (bucket value) as earlier.
If we have a match we look at that same entry in the offsets table and
grab the offset in the data for our final match.

Add AVX2 VEXTRACTI128 and VINSERTI128 instructions. Fix VPERM2I128 to be qualified with HasAVX2 instead of HasAVX. Mark VINSERTF128 and VEXTRACTF128 as never having side effects.

CMAKE_CONFIGURATION_TYPES is only set on Visual Studio generators.  For NMake CMAKE_BUILD_TYPE is used instead.

Add an option to pad an uleb128 to MCObjectWriter and remove the uleb128 encoding from the DWARF asm printer.

As a side effect we now print dwarf ulebs with .ascii directives.
