asiva@google.com fbc931e6a6 Report OOM errors instead of asserting on allocation failures when sending 
messages to other isolates.

asiva@google.com 01cc7d3cd2 - Canonicalize types, type_arguments only when the object is marked as being from the core libraries. 
- adjust the snapshot write buffer growth policy
- turn off the heap growth rate adjustments when reading from a snapshot.

hausner@google.com d4872a1499 Support initialized mixin fields across scripts 
Add capability to set parser to read tokens from different
scripts and token positions. This is used when the initializer
expression of a field resides in a different script.

asiva@google.com b053301ccf Fix for issue 1204. 
Do not allocate a buffer of 64KB by default when writing a message out. Start
with a much smaller buffer. FOr script and full snapshots the buffer
allocated remains 64 KB.

asiva@google.com fdbe32e24d Use external byte arrays for token stream, this moves the token stream out of the isolate heap. For full snapshots the external byte array points to the snapshot buffer thus incurring no extra space in the C heap either. 
Heap usage stats before this change is:
New space (0k of 32768k) Old space (1085k of 1280k) Code space (0k of 0k)

Heap Usage stats after this change is:
New space (0k of 32768k) Old space (947k of 1024k) Code space (0k of 0k)

A savings of about 138k.

asiva@google.com 5cbd276939 Make the parser agnostic to the TokenStream implementation. This is the first step towards compacting the token stream. 
Pull the data stream writer/reader code out of snapshot into a generic file so that it can be reused into the token stream compaction implementation.
