As there are not enough registers on ia32 to execute the platform-
independent code, the CL also adds ia32-specific code to
liftoff-compiler.cc. For this we first retrieve the memory index from
the stack, do a bounds check, and calculate the final address. Only
afterwards we pop all other values from the stack and pass them to the
platform-dependent code.

Out of the four listed reasons, two are obsolete now, since stepping
does not modify the code table any more. The first reason also cannot
happen any more, since removing a breakpoint will also patch the stack
of the isolate, and even if not, removing a breakpoint which is not set
will have no effect (not even a stack rewriting). The same applies for
the last listed reason.

This adds an internal property [[IsDetached]] to the inspector preview
of ArrayBuffer instances, which indicates whether the ArrayBuffer was
detached (i.e. transfered via `postMessage`). Previously it was rather
impossible to tell whether an ArrayBuffer was detached, you had to know
that V8 violates the ECMAScript specification and simply sets the
byteLength accessor to 0 upon detaching an ArrayBuffer (but even then it
was still impossible to tell whether that ArrayBuffer wasn't simply an
empty one from the get go).

meaning that each compiled function is finalized immediately after
compilation, rather than all functions being first compiled and then
finalized.
This is what we do on the main thread, and it reduces peak Zone memory
usage by being able to discard empty compilation Zones earlier.
One necessary functionality for this was being able to defer the
finalization of asm.js functions until the main thread pause, since
they can't be finalized off-thread -- previously we would just bail
out of doing the off-thread finalization if any inner function was
asm.js.

When an external string matches and internalized external string, we
want to deduplicate them. As part of that de-duplication, we check if
either a) the internalized string's resource is null (it's freshly
created because the original string was in new space) or b) they point
to the same data (in which case we don't want to dispose of the data).
However, when doing these checks we cast both the initial and the
internalized external string to the same type (one or two byte). So,
if a two-byte string finds a one-byte internalized string with
equivalent data, this cast will fail.
Since we only care about the external string resource being null or
equal to another during the above deduplication, the solution is
casting first to the more general ExternalString type, comparing
resources by address, and only casting to the more specific type
when needed (and we know that the types have to match by other
construction).

particular output. For example, this CL brings in CMakeBuilder for cmake
generation, but same infrastructure can be reused for generation of
amalgamated sources.
Things that are not yet automatically generated:
1) Automatic generation of config variables (from declare_args).
2) Dependency scanning. Since we only have limited number of targets,

Design doc:
https://docs.google.com/document/d/1szInbXZfaErWW70d30hJsOLL0Es-l5_g8d2rXm1ZBqI/edit?usp=sharing
V8 can already collect data about how many times each basic block in the
builtins is run. This change enables using that data for profile-guided
optimization. New comments in BUILD.gn describe how to use this feature.
A few implementation details worth mentioning, which aren't covered in
the design doc:
- BasicBlockProfilerData currently contains an array of RPO numbers.
However, this array is always just [0, 1, 2, 3, ...], so this change
removes that array. A new DCHECK in BasicBlockInstrumentor::Instrument
ensures that the removal is valid.
- RPO numbers, while useful for printing data that matches with the
stringified schedule, are not useful for matching profiling data with
blocks that haven't been scheduled yet. This change adds a new array
of block IDs in BasicBlockProfilerData, so that block counters can be
used for PGO.
- Basic block counters need to be written to a file so that they can be
provided to a subsequent run of mksnapshot, but the design doc doesn't
specify the transfer format or what file is used. In this change, I
propose using the existing v8.log file for that purpose. Block count
records look like this:
block,TestLessThanHandler,37,29405
This line indicates that block ID 37 in TestLessThanHandler was run
29405 times. If multiple lines refer to the same block, the reader
adds them all together. I like this format because it's easy to use:
- V8 already has robust logic for creating the log file, naming it to
avoid conflicts in multi-process situations, etc.
- Line order doesn't matter, and interleaved writes from various
logging sources are fine, given that V8 writes each line atomically.
- Combining multiple sources of profiling data is as simple as
concatenating their v8.log files together.
- It is a good idea to avoid making any changes based on profiling data
if the function being compiled doesn't match the one that was
profiled, since it is common to use profiling data downloaded from a
central lab which is updated only periodically. To check whether a
function matches, I propose using a hash of the Graph state right
before scheduling. This might be stricter than necessary, as some
changes to the function might be small enough that the profile data is
still relevant, but I'd rather err on the side of not making incorrect
changes. This hash is also written to the v8.log file, in a line that
looks like this:
builtin_hash,LdaZeroHandler,3387822046
