This patch unfies the finalization logic between the various unoptimized compilation paths in compiler.cc, taking the various post-processings and fixups needed for off-thread finalization and performing them in the same order for the other finalizations. It also unifies the general compilation path between streaming script compilation, main-thread script compilation, and main-thread lazy compilation, making the main-thread paths both use an iterative execution and finalization, and making all three use the same job helper methods and overall finalization helper.

UnoptimizedCompileFlags defines the input flags shared between parse and compile (currently parse-only). It is set initially with some values, and is immutable after being passed to ParseInfo (ParseInfo still has getters for the fields, but no setters). Since a few of the existing flags were output flags, ParseInfo now has a new output_flags field, which will eventually migrate to a ParseOutputs structure.

The native flag is a left-over from self-hosted JavaScript. Currently only the empty function and empty script are marked native. This CL removes the native flag from the ParseInfo, UnoptimizedCompilationInfo and its handling in the bytecode generator.

Previously when lazy source positions were enabled, source positions were immediately collected whenever an exception was thrown for every frame in the stack trace. This change makes source position collection trigger only when the source positions of a stack frame are actually accessed with the exception of the top frame which is still eagerly collected for now. Additionally when stack overflows occur during source position collection, the bytecode is marked with exception in the source_position_table field so it can be distinguished from the case where source position collection has never been attempted (undefined) or is not desired because the bytecode is for natives (empty_byte_array).

If enable_omit_source_positions is true (defaults to false), source position tables are not generated when compiling bytecode. They will then be regenerated when exceptions are thrown. This adds a new function Compiler::CollectSourcePositions which given a SharedFunctionInfo with bytecode but no source position table re-parses and regenerates the bytecode but this time with source positions collection enabled. Note this will reparse all inner functions that have previously been compiled since the preparse data is no longer available. With the flag enabled there still 18 test failures mostly related to debugging. v8: 8510 Change-Id: I46dff9818d8a89c901ba8ae8df94dcaca83aa658 Reviewed-on: https://chromium-review.googlesource.com/c/1385165 Commit-Queue: Dan Elphick <delphick@chromium.org> Reviewed-by: Toon Verwaest <verwaest@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Cr-Commit-Position: refs/heads/master@{#59595}

The parser object can now be created on a worker thread, therefore we shouldn't access global FLAGs during the constructor. Instead move them to the ParseInfo constructor and set the parser fields based on these. Also avoid accessing always_opt flags in bytecode-flags - instead accessing it in ParseInfo and propagating to the bytecode generator. Also gets rid of unused kUntrustedCodeMitigations flag in UnoptimizedCompilationInfo BUG=v8:8582 Change-Id: I6e6fdc8cc7865803cb5f334f652abc0e3e4cb3ce Reviewed-on: https://chromium-review.googlesource.com/c/1375918Reviewed-by: Leszek Swirski <leszeks@chromium.org> Commit-Queue: Ross McIlroy <rmcilroy@chromium.org> Cr-Commit-Position: refs/heads/master@{#58316}

Also update comments that'd gotten unnecessarily verbose over ten years of language development.

With the Ignition + Turbofan pipeline there is very little overlap between the data needed for unoptimized compilation and optimized compilation. As a result, it is cleaner to split up the CompilationInfo into UnoptimizedCompilationInfo and OptimizedCompilationInfo. Doing so also necessitate splitting up CompilationJob into UnoptimizedCompilationJob and OptimizedCompilationJob - again there is not much overlap so this seems cleaner.
