This adds a new trace macro to allow tracing to the ring buffer in release builds. It also performs normal tracing, too, like TRACE(n, ...). Converted a number of trace/log messages in the debugger to the new macro so we have this data when we get a core file. I've converted things that we've found useful lately, but this will be adjusted over time quite a lot as we discover new things that help us find problems more quickly, or find messages that turn our to be useless or spammy.
I was learning from @jdelong and he said that you should use
double quotes for local includes and angle brackets for library
includes. I asked why our code was the way it was, and he said he wanted
to clean it up. I beat him to it :)

This adds a new profiling mode for vector instruction
shapes. I'm planning on using this to identify any common cases that
may be worth special casing, like we do for simple SetM, CGetM, and
IssetM instructions. Instead of adding Yet Another Hashtable Stats
Map, I created a generic version and changed TRACE=punt:1 to use it as
well.
I also changed emitInterpOneOrPunt to use a more specific name.
Per @mwilliams' suggestion, this is the first stage in a staggered approach to replacing int64 with int64_t. More precisely I inserted "typedef ::int64_t int64;" in util/base.h and dealt with the consequences.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
