Sort entries and drop the try_index field. This simplifies lookup
of exception handlers when walking the traces on exceptions.

Collect info about try-statement nesting, and a list of
handled types in each catch clause. This will be used by

by any handler on the stack.

Put the PC (offset) of the deoptimization point and the deoptimization
reason in the DeoptInfo table.  The table entries are now triples of

srdjan@google.com caf04303f7 Deoptimization can occur at Dart calls (includes native calls to C) but not at runtime calls. This assumption (verified with Todd and Gilad) simplifies the implementation of lazy deoptimization considerably. 
Add flag --deoptimize-alot, which will lazily deoptimize all live optimized frames. Currently only the presence of deoptimization information is checked.

Add kDeoptAfter deoptimization point, which is the continuation for lazy deoptimization, after a call. Rename kDeopt to kDeoptBefore.

Removed a tests case that called into a native without properly setting up a Dart frame (Ok-d by Siva).

Native functions are not optimizable.

TODO: Split deoptimization information from DeoptimizationStubs. Check for redundant PcDescriptor information (what can be merged, especially at calls).

Add a count of live registers to each stackmap and add bits describing the
registers.  This allows untagged values in general purpose registers at
safepoints.

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.

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.

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.
