Many years ago those bailouts were seemingly added due to deferred
loading in [0]. Though it seems like those bailouts might've become
obsolete.
All places that clear the IC array on the function should run inside
a [NoBackgroundCompiler] scope, therefore ensuring no optimizing
compilations are done at that time. Those places also clear code,
therefore forcing re-compilation of unoptimized code (which will
re-create the ICData).

The background compiler no longer has bailouts due to something that
cannot be done on BG compiler and has to be done on mutator (was
originally introduced in [0])
All optimizing compilations can happen on the BG thread. Class
finalization and other things no longer cause a bailout on BG
compiler.
If e.g. invalidated field guards cause a compilation to be discarded, it
can be retried on BG compiler.

Whether a given isolate allows reloading is really a property of the
thread not the isolate (where it was before) or isolate group (where
it was moved to), so this CL moves it to Thread.
As the thread's stack is going down and up, NoReloadScope's might be
entered or exited, just as with our many other scopes, such as
NoOOBMessageScope/...
Longer term we might need to find a better mechanism to deal with
different OOB messages. For example: Reload as well as OOB messages
are disabled during static field initialization. Though that means *all*
OOB messages cannot reach the isolate during initialization of a static
field (which can do arbitrary amount of work).
This is part of making hot-reload work with isolate groups.

When going from Int64 through another representation back into Int64
you can discard a conversion if and only if it does not lose some
bits on the way. Previously we were checking for truncation flag, but
this is incorrect because it does not actually tell us anything about
about whether or not bits are going to be lost.
Instead, we should be checking the range of the source value.
In addition to fixing potential correctness issues, this CL actually
improves quality of code generated for Uint8 loads because it removes
a redundant chain of Int64->Uint32->Int64 conversions that follows
the load (which compiled 2 two redundant moves).

runtime.

The CFEs FormattedMessage always had two getters to get the text inside
one that would supposedly give an ansi formated version of the message
and one that would supposedly give a plaintext formated version of the
message. They both returned the same string, though, which would either
be with ansi escape codes or plain text depending on the environment at
compile time.
This CL fixes that by having both messages, and letting the reporting
(i.e. whenever the message is read) decide which to use. That way we
can - for instance - report errors with color if the terminal supports
it correctly when reusing a dill (and reissuing problems, but where the
terminal support changes) and if printing the problem to an html <pre>
field (like observatory does).
It also cleans up two different implementations of whether we think
the terminal supports colors or not, by deleting one of them.
This is the second try. Patchset #1 is the original.
Patchset #2(and possibly beyond) is the changes.
TEST=Existing test suites.

The async, off-stack part of DebuggerStackTrace::CollectAwaiterReturn's
stack unwinding incorrectly looked on the stack instead of following
the Closure's awaiter chain.
This caused the async stack traces to be truncated and missing any
async frames, in turn causing ShouldPauseOnException to incorrectly
conclude no handler frame existing.
This would affect any case where the exception handling was located
around any except for the inner most awaiter.
