turnidge@google.com 140a071acb Allow Observatory debugger to switch isolates. 
- Add the "isolate" command which allows the user to switch isolate by name or number.  Supports completion.

- Add the "isolate name" command which allows the user to rename an isolate.  Add the "setName" method to the service protocol to support this.  Isolates now have a debugger_name() in the vm.

- The new IsolateUpdate event notifies the client when an isolate name changes.

- When an isolate is updated, update the page's isolate too, so the navbar is accurate.

- Update isolate summary to display isolate number.

- Rework how the isolate's name is computed because we were getting garbagey names in the IsolateStart event (SpawnState was not yet set).

- Make sure that the debugger doesn't subscribe to events multiple times.

- "info isolates" is now "isolate list".

- Rework reporting of vm and isolate startTime in the service protocol and in Observatory.

- Fix bug in command completion when subcommands and other completions share common prefixes.

- Rework isolate accounting in the VM object in Observatory.  We now create Isolates in getFromMap rather than from IsolateStart events, per se.  Rewrite the isolate updating code.

- IsolateStart and IsolateExit events are now owned by the Isolate itself, rather than the vm.

- Return the actual result in pause/resume/etc.

- Add assertion in JSONStream::PrintProperty64 that the result fits in a javascript double.  Sigh.

- Stop sending GC events for the service isolate.  Add assertions to guard against this happening in the future.

- Misc improvements in error reporting.

vegorov@google.com ddbe93418d Work around GCC bug that results in incorrect simd128_value_t copying. 
Under certain conditions GCC on x86 decides to copy simd128_value_t through FPU stack.

For example Int32x4::value getter would contain the following code:

   212d5: d9 46 07              fld    DWORD PTR [esi+0x7]
   212d8: d9 46 0b              fld    DWORD PTR [esi+0xb]
   212db: 8b 46 03              mov    eax,DWORD PTR [esi+0x3]
   212de: d9 46 0f              fld    DWORD PTR [esi+0xf]
   212e1: d9 ca                 fxch   st(2)
   212e3: d9 5b 04              fstp   DWORD PTR [ebx+0x4]
   212e6: d9 5b 08              fstp   DWORD PTR [ebx+0x8]
   212e9: 89 03                 mov    DWORD PTR [ebx],eax
   212eb: d9 5b 0c              fstp   DWORD PTR [ebx+0xc]

This code is incorrect. For example an attempt to copy an int32_t value that
looks like sNaN will result in it turning into a qNaN which changes
the value being copied.

GCC bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58416

This was causing flakiness when people were running WebSocket related tests
locally on Dart VM binaries built with GCC as our WebSocket implementation uses
Int32x4 values to speed up payload masking/unmasking.

Bots were not affected because they are building with clang.

zra@google.com 2fe51715e5 Begins work on ARM64, first assembler test. 
Most new code is in constants_arm64.h and
{assembler,disassembler,simulator}_arm64.{h,cc}

The rest of the CL just #def's out tests, modifies status files,
and adds UNIMPLEMENTED functions, etc.
