In order to enable OSR, CheckStackOverflow IL instructions are attributed
with a non-zero loop depth. The original loop depth is passed as operand
of CheckStack bytecode instruction.

This is especially important for multiple entry-points in AOT mode, since without the type
information we can't inline certain intrinsics (because they would have to de-opt).

Makes time spent in interpreted versus compiled Dart code visible in Observatory's pie chart. Will allow the profiler to know whether to start a stack walk from the machine code FP or the interpreter's FP.
Remove dead Dart 1 frontend tags. Add tag for loading bytecode.

Previously MoveSpecial bytecode instruction used unsigned 8-bit A field
to encode target local variable index. This is too restrictive as we allow
signed 16-bit local variable indices.
After this change MoveSpecial has A_X encoding, with A field used for
special index (0 or 1), and signed 16-bit X field used for target local.

Previously, we only stored a reference to the originating Typedef declaration
and is thus loosing the originating type arguments. We need these type arguments
in various places, including diagnostics and bounds checks.
Note: this CL maintains backwards compatibility wrt to the Dart API of
FunctionType. I'll update the API in a follow-up CL.

Similar to how we treat catch entry instructions, this cl adds new
function and osr entry instructions. The [FunctionEntry] and
[OsrEntry] - just like [CatchBlockEntry] - have now their own initial
definitions. The [GraphEntry] has only initial definitions for
constants.
Explicit phis are inserted for all parameter / special parameter
instructions if necessary.
Future work is:
a) Minimize parallel moves due to the phis on parameters
b) Cleanup frame setup: Move it entirely into FunctionEntry/CatchEntry
(instead of the split version we have now)

If a field is initialized with null (either explicitly or implicitly),
field store can be omitted in bytecode. In such case, bytecode should
still convey the information about this initialization to VM for
field guards to work correctly.
