Add suppose for compiling non-eager, non-top-level inner functions in
parallel, using the compiler dispatcher. This behaviour can be enabled
with --parallel-compile-tasks-for-lazy.
There are a couple of consequences:
* To support this we need support for off-thread ScopeInfo
deserialization, so this adds that too.
* The previous --parallel-compile-tasks flag is renamed to the more
descriptive --parallel-compile-tasks-for-eager-toplevel.
* Both parallel-compile-tasks flags are moved onto
UnoptimizedCompileFlags so that they can be enabled/disabled on a
per-compile basis (e.g. enabled for streaming, disabled for
re-parsing).
* asm.js compilations can now happen without an active Context (in
the compiler dispatcher's idle finalization) so we can't get a
ContextId for metric reporting; we'd need to somehow fix this if we
wanted asm.js UKM but for now it's probably fine.
* Took the opportunity to clean up some of the "can preparse" logic in
the parser.
