Florian Schneider 18faa55764 Fix lazy deoptimization from deferred code. 
Insert enough padding to ensure enough space for when lazy deoptimization occurs
from the last deferred code object.

Also, speed up ia32 disassembler to avoid tests timing out.

Daniel Andersson a1bc527306 Migrate logging infrastructure Isolate->Thread 
This enables thread-safe logging (e.g., ISL_Print, which will soon be renamed to THR_Print), which is needed for concurrent
marking (DetachCode) and compilation.

Make finalization of GC marking tasks concurrent, now that it's thread-safe.

Todd Turnidge cc981c8246 Don't use %p when generating disassembly in vm service. 
Evidentally it is platform dependent -- it seems to include the 0x
prefix on mac but not on windows.  I've switched to using %" Px "
instead.

This will fix bug 24038.

koda@google.com e3a345a84b Rename NoGCScope -> NoSafepointScope. 
The old name makes less sense in the context of concurrent GC (and multiple threads in general).

Document the intended semantics of this (DEBUG-only) guard scope.

johnmccutchan@google.com f2333f63a5 Add Function based profile tree 
Profiler improvements:
- Track Functions in profile and build Function based trie
- Associate code objects with functions
- Created cpu_profile.dart library
- Major speed improvements for disassembly view
- Fix truncation of disassembly comments
- Ability to get code object ticks from disassembly view
- Inlining mini-map in disassembly view.
- Remove a bunch of unused data from profile service response
- In some cases a caller PC that is better than the PC marker is inserted into the stack trace
- Inlined functions are expanded
- Ability to clear profile
- New flag '--keep_code' which keeps deoptimized code around for use by the profiler.

General fixes:
- Fix caching in service library
- Remove pubspec.yaml before running pub get
