c17e860569 [turbofan] Remove type feedback from AstGraphBuilder pipeline.
The AstGraphBuilder pipeline is only used for asm.js now, so the whole
type feedback mechanism is essentially dead code currently, thus we
better nuke it.

292c4a0a2a [ignition] Replace branch+loop analysis with a single pass
Now that we have a JumpLoop bytecode, we can heavily simplify the
branch/loop analysis by assuming that only JumpLoop bytecodes are
backwards edges, and performing the loop analysis as a single
(backwards) pass.

This allows us to get rid of the branch analysis entirely, and builds a
framework to do liveness analysis in the same pass.

172f501233 [wasm] Implement official wasm text format
When disassembling functions for the inspector, we used an internal
text representation before. This CL implements the official text
format like it is understood by the spec interpreter.

Example output:
func $main (param i32) (result i32)
block i32
  get_local 0
  i32.const 2
  i32.lt_u
  if
    i32.const -2
    return
  end
  get_local 0
  call_indirect 0
end

ae0e92219b Properly define v8_enable_inspector and its override in GN.
Instead of directly using v8_enable_inspector_override from
build_overrides/v8.gni in all the GN configs, set a v8_enable_inspector
variable based on v8_enable_inspector_override and use that everywhere.
This is the more common pattern seen in over projects, and reduces the
need to include //build_overrides/v8.gni in many files.

f91178e823 [ignition] Add a reverse bytecode iterator
This pre-calculates and stores a vector of bytecode offsets, and then allows
one to iterate over it backwards. This could probably be adapted to a
bidirectional/random access iterator if we wanted to, but for now reverse
is all we need.

248a3e25e9 [refactoring] Pull AccessorAssembler out of CodeStubAssembler
The new AccessorAssembler encapsulates all the functionality that's
specific to building LoadIC/StoreIC stubs.
There are two header files (accessor-assembler.h and
accessor-assembler-impl.h) so that clients of the assembler can include
the one, and subclassing assemblers can include the other.

a18be72c8e Add v8_os_page_size flag for cross compilation
When generating snapshot on a machine with a different page size than
the target machine, we can run into problems as the v8 page area size
changes. This is because v8 has page guards which depend on os page
size, so if the target has larger os page, v8 page area is smaller and
may not fit the contents.

The solution proposed here is adding a flag, v8_os_page_size, that
would, if used, override local os page size and use the one specified
during snapshot generation.

c3a6ca68d0 This CL enables precise source positions for all V8 compilers. It merges compiler::SourcePosition and internal::SourcePosition to a single class used throughout the codebase. The new internal::SourcePosition instances store an id identifying an inlined function in addition to a script offset.
SourcePosition::InliningId() refers to a the new table DeoptimizationInputData::InliningPositions(), which provides the following data for every inlining id:
 - The inlined SharedFunctionInfo as an offset into DeoptimizationInfo::LiteralArray
 - The SourcePosition of the inlining. Recursively, this yields the full inlining stack.
Before the Code object is created, the same information can be found in CompilationInfo::inlined_functions().

If SourcePosition::InliningId() is SourcePosition::kNotInlined, it refers to the outer (non-inlined) function.
So every SourcePosition has full information about its inlining stack, as long as the corresponding Code object is known. The internal represenation of a source position is a positive 64bit integer.

All compilers create now appropriate source positions for inlined functions. In the case of Turbofan, this required using AstGraphBuilderWithPositions for inlined functions too. So this class is now moved to a header file.

At the moment, the additional information in source positions is only used in --trace-deopt and --code-comments. The profiler needs to be updated, at the moment it gets the correct script offsets from the deopt info, but the wrong script id from the reconstructed deopt stack, which can lead to wrong outputs. This should be resolved by making the profiler use the new inlining information for deopts.

I activated the inlined deoptimization tests in test-cpu-profiler.cc for Turbofan, changing them to a case where the deopt stack and the inlining position agree. It is currently still broken for other cases.

The following additional changes were necessary:
 - The source position table (internal::SourcePositionTableBuilder etc.) supports now 64bit source positions. Encoding source positions in a single 64bit int together with the difference encoding in the source position table results in very little overhead for the inlining id, since only 12% of the source positions in Octane have a changed inlining id.
 - The class HPositionInfo was effectively dead code and is now removed.
 - SourcePosition has new printing and information facilities, including computing a full inlining stack.
 - I had to rename compiler/source-position.{h,cc} to compiler/compiler-source-position-table.{h,cc} to avoid clashes with the new src/source-position.cc file.
 - I wrote the new wrapper PodArray for ByteArray. It is a template working with any POD-type. This is used in DeoptimizationInputData::InliningPositions().
 - I removed HInlinedFunctionInfo and HGraph::inlined_function_infos, because they were only used for the now obsolete Crankshaft inlining ids.
 - Crankshaft managed a list of inlined functions in Lithium: LChunk::inlined_functions. This is an analog structure to CompilationInfo::inlined_functions. So I removed LChunk::inlined_functions and made Crankshaft use CompilationInfo::inlined_functions instead, because this was necessary to register the offsets into the literal array in a uniform way. This is a safe change because LChunk::inlined_functions has no other uses and the functions in CompilationInfo::inlined_functions have a strictly longer lifespan, being created earlier (in Hydrogen already).

6df8096a00 [Tracing] Implement TracingCategoryObserver.
This patch implements TracingCategoryObserver to set global flag when a V8
specific category is enabled. Previously, we set a global flag each time when we
encounter a top level trace event, and use it as a global check. With this
patch, we can set a group of flags when tracing is enabled; besides, we make
V8 tracing feature use V8 flags instead of defining its own flag in a messy way.

With this patch, whatever V8 flag we want to imply in tracing, we define another
integer flag, and the original V8 flag will set it to 0x01 when passing by
commandline, tracing will set it to 0x10 when we start tracing and reset the bit
when we stop tracing.

610c0d75c8 New zone-backed list datastructure to replace ZoneList
Since ZoneLists are essentially non-standard ZoneVectors and have a bad
growing behaviour (ZoneList-allocations make up ~50% of website parse
zone memory) we should stop using them. The zone-containers are merely
a clean-up, with none of them actually better suited to be used with
zones. This new datastructure allows most operations of a LinkedList (
except pop_first and insertAt/removeAt) but uses about the same memory
as a well-initialized ZoneVector/ZoneList (<3% overhead with reasonably
large lists). It also never attempts to free memory again (which would
not work in zones anyway).

The ZoneChunkList is essentially a doubly-linked-list of arrays of
variable size.

Some test-results where I tried storing 16k pointers in different list
types (lists themselves also zone-allocated):

List type                       Zone memory used   Time taken
-----------------------------------------------------------------------
Zone array (for comparison)     131072 B

Ideally initialized ZoneList    131088 B           0.062ms

ChunkZoneList                   134744 B           0.052ms <--new thing

ZoneDeque                       141744 B

ZoneLinkedList                  393264 B

Initially empty ZoneList        524168 B           0.171ms <--right now

ChunkZoneList only push_front   524320 B

df981a9ff5 [crankshaft] Refactor kAllowUndefinedAsNaN to kTruncatingToNumber.
The meaning of the HValue::kAllowUndefinedAsNaN is actually ToNumber
conversion (except for the uses in HBranch and HCompareHoleAndBranch,
which were confusing and useless anyways), so fix the naming to match
that.

Also properly integrate the handling of this flag with the existing
truncation analysis that is run as part of the representation changes
phase (i.e. where we already deal with truncating to int32 and smi).

This is done in preparation of allowing Crankshaft to handle any kind
of Oddball in the ToNumber truncation, instead of just undefined for
truncation ToNumber and undefined or boolean for ToInt32. It also helps
to make Crankshaft somewhat more compatible with the (saner)
implementation in TurboFan.
