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.

These bytecode instructions are added in order to shrink constant pools
and reduce time spent for reading constant pool entries.

Number of checked arguments is corrected in ICData objects created when
reading bytecode, both for instance and static calls.
InstanceCall1 and InstanceCall2 bytecode instructions are replaced with
InstanceCall which works for any number of checked arguments. This makes
decision on number of checked arguments internal to VM and it is no longer
exposed to bytecode.

In addition:
* Use InstanceCall1 instead of InstanceCall2 for now as InstanceCall2
requires ICData objects with 2 checked arguments.
* Remove try-catch around bytecode generation as all operations are
supported and silent fallback is no longer needed.
