389fa6c38d 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.

4c8a7dc833 Allow stat += 0 without activating the stat. 
For me, this is a nice convenience. We generally want grep to match
stats output only when the event has occurred.

63f8158cff Introduce namespace-scope functions to enable LLVM statistics without 
passing the command-line parameter "-stats" and to print the resulting
statistics without calling llvm_shutdown().

2d65e89f30 Use atomic operations when accessing statistics, and make the lazy initialization of statistics actually threadsafe.

2a23a4e495 Use an explicit llvm:: prefix in the STATISTIC macro, so STATISTIC can still be 
used when "using namespace llvm" is not in effect.

e0b1ee937a Don't attribute in file headers anymore. See llvmdev for the 
discussion of this change.  Boy are my fingers tired. ;-)

87e0f0787e eliminate constructor from Statistic class. It is now impossible to get a 
static constructor for them :).   Transition complete.

3b18f0e184 Added operator methods to the Statistic class; some LLVM projects depend 
on these.

c18ec8716e Refactor statistic a big and introduce a horrible-but-necessary macro 
(STATISTIC), which allows us to define statistics that don't introduce
static ctors into the .o files.  I'm migrating code over to use this
incrementally.

9c52dc6c34 Change the implementation of statistic to not need destructors at all. 
Instead, the stat info is printed when llvm_shutdown() is called.
These also don't need static ctors, but getting rid of them is uglier:
still investigating.  This reduces the number of static dtors in llvm from
~1400 to ~750.

a396e6d9ba Add some out-of-line virtual dtors so that the class has a "home", preventing 
vtables for (e.g.) Instruction from being emitted into every .o file.

c4abcbefb1 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.
