71754ebe81 Add multithreading test for SamplingCircularQueue, fix implementation. 
This is for the case of Linux, where sampling is done using SIGPROF
signal handler which is executed in the context of an interrupted
thread. In this case, my previous implementation with TLS doesn't
work.

This change fixes an assert we hit when we recognized a fast smi loop
with a parameter as the loop variable.

ec974ddb50 Fix bug when generating a fast smi loop. 
We may encounter an invalid frame after generating code
for the loop body in case the loop body ends in an unconditional
return. Before setting the type information for the loop variable
we need to check for a valid frame.

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.

800b6df2a6 Correct handling of adding a string and a smal integer 
The fast case of looking up the string convertion of the smi did not handle the case where left/reghe operands could be in eax/edx instead of edx/eax which is the default.

Also got rid of creating an internal frame for calling string and instead patched the argument on the stack and performed a tail call.
