''' 'inline_helpers' ''' - provides a mechanism to inline various VM helpers

The optimization examines every HIR instruction and searches for HIR opcodes that lead to
generation of VM helpers. Every suitable for the optimization instruction is replaced with
a direct call of a special Java method. Finally the optimization calls inlining of this method.
The body of the method used as a replacement for complex HIR instruction must be provided
by VM component. 
The method can be can be written using [http://rvm.codehaus.org/docs/api/org/vmmagic/unboxed/package-summary.html
