Trace String.prototype.substring for two-arg case.
...
* Export str_substring as js_str_substring.
* Add basic String_p_substring builtin (only handle end > begin, both in range).
* Add String_p_substring_1 builtin for the missing-end case.
* INS_CONST for named constants in traces.
* Support boxing of strings.
* Support CALLPROP with primitive this.
* Support traceable natives which require cx and this.
* Support fallible traceable natives.
* Fix JSOP_LENGTH to use i2f on result (need that everything-is-doubles T-shirt).
* Add strings test.

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.
