Track the type of guards and react accordingly if we bail out on them. Guards that protect against out-of-memory conditions don't try to grow the tree. Instead we just resume the interpreter.

If we see a f2i(UnboxDouble) chain, simplify it to UnboxInt32 which does the conversion internally. This also enables a fastpath to read 31-bit jsval integers from arrays.

Smarter speculative demotion of numbers to integers and promotion of the trace seems to require actual doubles. If the number at entry looks like an int we make the slot an int and compile as such. If the loop-tail proves the slot to be a double, we recompile the trace. Currently such miss-speculation cannot be handled on secondary traces since we are currently unable to recompile the primary trace. Such secondary traces are blacklisted.

Don't try to demote slots on secondary traces (we have to recompile the primary trace as well for that, which we currently don't do.)

Eliminate EntryRegs. Its not safe to keep a reference to the entry SP since we might extend the tree from a different outer stack frame. Instead just store the entryStackDepth.

Backed out changeset a58e7ce6eb7f. stack(0) is wrong, if at all it should have been stack(-(1 + argc)). But anyway, its impossible to write through to the frame via set() at that point because leaveFrame() doesn't actually modify cx->fp. We need to wait for the interpreter to do so. Until then nativeFrameOffset produces incorrect values and the assert fails in set.

Maintain a separate frame for globals using InterpState->gp.
This will allow nested loops to access the globals interned by outer loops while at the same time sharing parts of the stack of the outer loop.
