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 6c7d65e482 Reduce space used for stackmaps. 
Only allocate space for the bits covered by the stackmap, instead of
for the backing store of the utility class that built it.  Fix a bug
where the size in bytes was multiplied by the word size in bytes.

Also do some cleanup of the stackmap code and renaming in the tests.

regis@google.com 12de02cbab Associate the correct type to method receivers (instead of Dynamic type). 
Properly name the first implicit parameter to factories as ':type_arguments'
(instead of 'this', which made it accessible to user code).
Various cleanup.

turnidge@google.com a3a73029f0 Consolidate a few fields in RawFunction using bitfields. 
Remove kAbstract from the list of function kinds.  It now has its own
dedicated bit.  This allows us to distinguish abstract methods from
abstract getters and setters.

kmillikin@google.com cc619aa2c9 Change the stackmap builder API. 
It is inconvenient for the stackmap table builder to use a singleton bitmap
for all safepoints in a code object.  Instead, split the bitmap from the
table builder and allow a bitmap per safepoint.

Take this opportunity to rename StackmapBuilder => StackmapTableBuilder
because it builds the entire table of stackmaps for a code object.

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.

asiva@google.com 2d3775a1b1 Resubmit change 6302 after fixing the compiler warning on older GCC compiler versions: 
Change 6302 description:
- Wire the stack frame iterator to use stack maps for traversing objects if
there are stack maps in the code object. If there are no stack maps it still
does the old style stack frame traversal between fp and sp looking for tagged
pointers.
- Added a mechanism to be able to iterate over the code space and look for a
particular object.
