b148282b56 String search performance improvements: 
* Using memchr for first/only char lookup is faster than hand-coded
   loop. It processes one machine word per iteration so it helps even
   more on x64.

 * Tweaked badness computation in simple search. We pay only for the
   first char memchr scans, not for all of them.

ce9298029d Implement circular queues for the C++ version of CPU profiler. 
Circular queues serve as a transport for communicating between
VM, stack sampler and analyzer threads. Logging requirements
for VM and stack sampler are completely different, that's why
I introduced two different versions of CQs.

889cbe55b8 Fix a bug in the regexp caching. Also add a few more places to 
cache.  We now cache most of the places where Opera cache and
one or two where they do not cache for some reason.  Since
these optimizations aren't necessarily useful on real code we
may remove them if and when the Dromaeo website makes the
benchmarks harder to game.
