kmillikin@google.com 94a5b82f60 Make stackmaps store their actual length. 
This allows stackmaps with varying lengths in the same function, necessary
for the way we plan to support bitmaps for saved live registers.

kmillikin@google.com f440cf8292 Fix an off-by-one error in the stack frame iteration. 
When using a stackmap, we mapped stackmap index 0 to the code slot in the
frame.  This code is still unused, but judging from the test the intent is
to map index 0 to the first local slot in the frame.

Add a RawBitmap object and a bitmap builder.
