This pseudo-instruction marks the beginning of a region of byte code that
can be copied into a new method, termed an "outlineable" chunk.  The size of
the Java stack must be the same at the start of the region as it is at the
end of the region, any value on the stack at the start of the region must not
be consumed by an instruction in the region of code, the region must not
contain a return instruction, no branch instruction in the region is
permitted to have a target that is outside the region, and no branch
instruction outside the region is permitted to have a target that is inside
the region.
The end of the region is marked by an OutlineableChunkEnd pseudo-instruction.
Such a region of code may contain other outlineable regions.
