Add the concept of peer fragments to nanojit. Each loop fragment can have a number of peer fragments, which we can use to have several different specialized variants of a loop (i.e. for different types). The makefile doesn't pick up the change to Fragmento.h, so make sure you clobber by hand or you will end up wasting an hour of your life in gdb (like me.)

Hands down the hardest bug I had to debug in TM so far. Make sure to read back any registers an inner tree might have changed before writing out the typemap for the nested_exit guard, otherwise we might be pointing to old stale pre-(inner-)loop state and pick an incorrect (in this case too narrow) type. fannkuch=2.8x with this.

- Avoid unnecessary FASTCALL builtin wrappers for existing js_* library-private or friend functions, which could be (and now are) fastcall (JS_FASTCALL). A couple of builtins avoid name collisions by using js_Fast instead of just js_ as their name prefix.
...
- Use GCF_DONT_BLOCK from fastcall builtins that call into the GC allocator (mostly; a few places need help still, or better: need to avoid allocation).
- Cope with C clients of jscntxt.h and its include files (these hacks should go away).

Added a callstack that will track the pc of the call that caused a function call to be inlined. This is necessary to recover from deep side exits inside inline functions. The callstack is subject to store elimination, so unnecessary stores to the stack will go dead automatically during compilation (i.e. if we inline a function that doesn't have side exits.)
