2619ccd1a0 Move post-mortem constants from accessors table to constants table 
Some post-mortem metadata constants that are not offsets to objects'
properties were incorrectly defined in the accessors table. This change
fixes it by moving them from the accessors table to the constants table.

56a0a797f2 Update post-mortem metadata generation 
mdb_v8, a post-mortem debugger for Node.js, now uses JSArrayBuffer's
backing_store property and JSArrayBufferView's byte_offset property to
get access to the content of Buffer instances in node (which are
Uint8Array instances). This change adds post-mortem metadata for these
two properties.

This change also fixes a typo in
inobject_properties_of_constructor_function_index_offset that was added
to gen-postmortem-metadata in a previous change. It should be named
inobject_properties_or_constructor_function_index instead.

357e6b99ee Add ScopeInfo constants to post-mortem metadata 
mdb_v8, a post-mortem debugging tool for Node.js, allows users to
inspect ScopeInfo structures in order to get more information about
closures.

Currently, it hardcodes the metadata it uses to find this information.
This change allows it to get this metadata from the node binary itself,
and thus to adapt to future changes made to the layout of the ScopeInfo
data structure.

ff7d70bf41 Update BitField3 type in gen-postmortem-metadata.py 
Since https://codereview.chromium.org/272163002, BitField3 is a raw
uint32 field, and not a SMI anymore.

Update tools/gen-postmortem-metadata.py so that post-mortem tools can
work with versions of V8 that shipped after that change.

This change was merged in github.com/joyent/node right before node
v0.12.0 was released.

5434d052f1 fix gen-postmortem-metadata.py for kInObjectPropertiesOffset

Map::kInObjectPropertiesOffset was been replaced by
kInObjectPropertiesOrConstructorFunctionIndexOffset in
