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.

This CL contains 2 fixes:
* Instantiator type arguments for factory constructors are calculated
using factory's type parameters and not class type parameters
(as factory's body uses factory's type parameters in kernel AST)
This improves reuse of instantiator type arguments in factory
constructors (optimization).
* Result of _AssertionError::_throwNew call is dropped off the stack.
Although control never returns from _throwNew, this fix is needed
to maintain correct stack balance while compiling bytecode.

Bytecode for 'assert' statement includes source positions, which are
different on Linux and Windows due to different newline characters.
This causes bytecode generator tests to fail on Windows, as expected
output includes source positions calculated on Linux.
To avoid these failures, new flag 'omitSourcePositions' is added
to bytecode generator and used in the bytecode generator test.

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.
