git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143923 91177308-0d34-0410-b5e6-96231b3b80d8

Add a new dwarf accelerator table prototype with the goal of replacing
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.

build/cmake: Use tblgen macro directly instead of llvm_tablegen, which just
added a layer of indirection with no value (not even conciseness).

Emit declarations before definitions if they are available. This causes DW_AT_specification to
point back in the file in the included testcase. Fixes PR11300.

Reformatting changes to get rid of blank lines, put code on one line, and to

Refactor the MCContext so that it's an ivar instead of a local which is passed
around. This is important for some future work as well.

Speculatively revert "DeadStoreElimination can now trim the size of a store if

build/Make: Integrate llvm-build into Makefiles.
 - Basically, we coordinate with llvm-build to create a Makefile fragment we can
   easily use. For now, nothing is wired in except the support to automatically
   regenerate this file when necessary.
