koda@google.com c7e9e048ed Rename Thread -> OSThread.
It's a collection of static utility methods for primitive operations on OS threads.

Make room in the namespace for upcoming class that will represent all the complex state of a VM thread.

zra@google.com 816bf5af2e Fixes for the profiler on arm64.
On arm64, in Dart code, R18(SP) is the stack pointer.
In C++ code, R31(CSP) is the stack pointer.
The profiler must choose the right one when performing
its bounds checks.

This change also fixes a bug in the InvokeDartCode stub
on arm64 so that CSP is set to the Isolate's stack
limit immediately, rather than a bit later. When it was
set a bit later, if a profiler interrupt came in in the
interim, the stack would be smashed.

johnmccutchan@google.com 86c55f4fde Keep list of existing isolates.
List is only updated when isolates are created / destroyed.
ThreadInterrupter now walks list of isolates.
Scheduling an isolate for interrupts is now lockless.
Setting a current isolate is now lockless.
Working on Linux, Mac, and Windows.
Assert that the isolate isn't on two threads at once.

johnmccutchan@google.com 919dc2d6eb * Introduce ThreadInterrupter which calls a TLS set callback when thread is interrupted.
* Threads can only register and unregister themselves with ThreadInterrupter.
* Profiler is no longer involved in interrupting threads. It's just a callback and the buffer.
* Profiler operates lock free using an atomic operation to reserve sample in sample buffer.
* Linux, Mac, and Windows done.
