Matthias Braun 98ea88be42 Statistic: Add machine parseable json output 
- We lacked a short unique identifier for a statistics, so I renamed the
  current "Name" field that just contained the DEBUG_TYPE name of the
  current file to DebugType and added a new "Name" field that contains
  the C++ identifier of the statistic variable.
- Add the -stats-json option which outputs statistics in json format.

Peter Collingbourne 4cfa086df2 Support: Clean up TSan annotations. 
Remove support for Valgrind-based TSan, which hasn't been maintained for a
few years. We now use the TSan annotations only if LLVM is compiled with
-fsanitize=thread. We no longer need the weak function definitions as we
are guaranteed that our program is linked directly with the TSan runtime.

Apparently, the style needs to be agreed upon first.

Benjamin Kramer 0b6eb591a4 [C++11] Replace LLVM atomics with std::atomic. 
With C++11 we finally have a standardized way to specify atomic operations. Use
them to replace the existing custom implemention. Sadly the translation is not
entirely trivial as std::atomic allows more fine-grained control over the
atomicity. I tried to preserve the old semantics as well as possible.

Jan Wen Voung 7857a64909 Disable statistics on Release builds and move tests that depend on -stats. 
Summary:
Statistics are still available in Release+Asserts (any +Asserts builds),
and stats can also be turned on with LLVM_ENABLE_STATS.

Move some of the FastISel stats that were moved under DEBUG()
back out of DEBUG(), since stats are disabled across the board now.

Many tests depend on grepping "-stats" output.  Move those into
a orig_dir/Stats/. so that they can be marked as unsupported
when building without statistics.

Chandler Carruth ed0881b2a6 Use the new script to sort the includes of every file under lib. 
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

Nick Lewycky 897a57ecda Silence tsan false-positives (tsan can't track things which are only safe due to 
memory fences) in statistics registration, which works the same way that
ManagedStatic registration does.
