Change sp_adj in guards to always reflect the current stack depth, so if we enter a trace/loop with something on the stack, sp_adj will reflect always at least that minimum amount.

Major shakeup of the interning code for globals. Globals are now detected on demand as they are used and the slots are noted in treeInfo->globalSlots. At the same time the type is recorded in treeInfo->globalTypeMap. The stack type-map is maintained separately in treeInfo->stackTypeMap. All these structures are lists and are maintained as List<T> objects. Imports for globals can appear at the top (if we have already seen some imports for the loop header and are recompiling), or on the fly for lazily found values. We no longer intern all global properties that happen to match a name in the current function, and we also support inlining of functions that touch globals that are not used in the method where the trace started in.

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.

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.

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.
