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 adds the option to peel off the first iteration of inner loops. Loop peeling is off by default and can enabled by a flag. It also requires building a flow graph. As part of this I added the possibility to clone AST nodes.

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.

* 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.
