11ba497cd8 Delegate getting current wall-clock time to the Platform interface.
To enable executing code in a context of a particular time or date (e.g. when
codepath depends on whether it's say evening or New Year) there is a need for
a way to provide it bypassing actual system time.

ef8baffa6c [Parsing] Remove parse-task support.
Parse tasks are not currently used, and will need to be changed significantly
for background compilation, so we remove them for now.

b4e55e9443 [Compiler] Decouple CompilationInfo and ParseInfo.
Don't hold a pointer to parse_info in compilation_info, and instead explicitly
add the fields needed in compiation_info. The intention is to make ParseInfo
only actually needed for parsing, and eventually make it possible to compile
with only a CompileInfo.

ad09fd60d6 [compiler-dispatcher] Pass isolate to main thread step
Rather than storing the isolate in compiler dispatcher jobs, which gets
weird for jobs that are entirely off-thread, instead pass the isolate
in when stepping on the main thread.

This makes it clearer which steps must be executed on the main thread,
as they require the caller to explicitly give them access to the
isolate.

3b334b73e9 [Compiler] Remove ability to create CompilerDispatcher jobs from parsed literal.
The approach to creating compiler dispatcher jobs for inner functions after
they had been parsed didn't provide the startup benifits we hoped for due
to the need to hold onto the whole zone memory AST while waiting for the
jobs to complete.

This CL removes the ability to create these compilation jobs (which was never
enabled by default anyway). Going forward we will potentially use the
parser task approach to parse+compile inner functions in their own job.

3e47cb87d6 [Turbofan] Use bytecode size for inlining heuristics.
Inlining heuristics in Turbofan used ast node count. Bytecode size
is a better approximation of the size of the graph than the
ast node count. This cl changes the heuristics to use the bytecode
size instead. Also removing the ast_node_count filed in the shared
function info. It was used only for the inlining heuristics.

Also removed the max_inlined_source_size flag which is no longer used.

9b51273278 Remove "calls eval" bit from ParseInfo and PreParseData
There's no reason to keep track, for a preparsed function itself,
whether that function calls eval. All that matters is that the ancestor
scopes are marked as having an inner scope which calls eval. The function
will have its "calls eval" bit persisted if/when it's fully parsed.

The only "behavioral" change in this patch is the removal of a DCHECK.

96009d28dc [Compiler] Avoid stepping a job in EnqueueAndStep if job is already enqueued.
If a job was already enqueued, EnqueueAndStep would still step the job one
more step. However, since it didn't take the job out of the
pending_background_jobs pool, the job could get picked up by a background
thread which would try to step it, but it the job is now at a step which
can't be run on the background.

handles in a deferred handle scope and keep the deferred handles alive with

1fc93f2e2d [Compiler] Enable use of seperate zones for parsing and compiling.
In order to allow parallel compilation of eager inner functions, we need to
seperate the zone used for parsing (which will be shared between all the
parallel compile jobs) and the zone used for compilation. This CL changes
CompilationInfo to require a zone (which can be different from the zone in
ParseInfo). We then seal the ParseInfo zone after parsing and analysis is done
to prevent any further allocation in that zone, so that it can be shared
(read-only) with the parallel compile jobs.
