a449f09fad [Memory] Create memory management API in v8::internal.
- Creates a memory management API in v8::internal, which corresponds
  to the existing one in base::OS.
- Implements the new API in terms of the old one.
- Changes all usage of the base::OS API to the one in v8::internal. This
  includes all tests, except platform and OS tests.
- Makes OS:: methods private.
- Moves all LSAN calls into the v8::internal functions.

25d4f93740 Reland "MIPS[64] Implementation of MSA instructions on builtin simulator"
This is reland of 3e0bf580e8
Original change's description:
> This commit is a step toward enabling test-run-wasm-simd tests for MIPS.
> 36 of those were failing in V8 builtin simulator because some instructions
> were not implemented.  Also there are minor fixes to some of the already

ee4fe8963c [wasm] trap handlers: fall back on old signal handler
This is primarily needed to test D8 under ASan. ASan installs a signal handler
early in the process startup to show stack traces from crashes. We need to make
sure that if V8 does not handle a signal then the existing handler gets a
chance.

This change only applies when using V8's default signal handler. When
integrating with the embedder's signal handler the behavior is unchanged.

329f694678 [cleanup] Replace List with std::vector in api.
The members of HandleScopeImplementer are copied with memcpy when
the isolate is transferred to another thread. List contained some
primitives which allowed us to manually free the backing store, which
was needed in order to ensure that threads would not hold on to
old pointers and use them later. With std::vector, we can't do that.

Here we change the HandleScopeImplementer to instead use a custom
structure DetachableVector, which contains a std::vector but allows
manual detaching and freeing of the backing store. This allows us to
maintain the old behavior.

110d9ab005 [wasm] A simple allocator datastructure for off-the heap
We'll use this allocator in a follow-up CL to:
- allocate speculative sizes of memory for a module that's being
compiled (e.g. 2*size of wasm code).
- each module will own such a sub-pool, and then use it to allocate
contiguous chunks of memory for code.

The underlying assumptions for the chosen allocation strategy is that:
- the allocation granularity for pools is 1 page, so that no one page
is owned by more than one wasm module
- typical pool sizes (given module sizes) are multiple pages.
- modules and module instances are typically few and long lived. Typically,
we expect one module and one instance. 

This means we shouldn't expect fragmentations that lead to code being
non-allocatable, or prohibitively many ranges.

The data structure just manages ranges of addresses. Virtual memory management
will be separate, as part of the responsibility of a "WasmHeap"
that will be introduced in the future. So will concurrency control.

84dc3679d1 Move helper struct from logging.h to template-utils.h
I want to reuse the PassType helper in another CL, thus move it from
logging.h to template-utils.h, and rename it to pass_value_or_ref to
match other helpers there.
Also, add a boolean template parameter to declare whether array
dimensions should be removed. The default is to do so, which helps to
reduce the number of template instantiations by always passing arrays
as pointers.

Also, fix the usages in logging.h to actually use that helper when
instantiating other template functions. This will reduce the number of
instantiations.

And finally, we now have unit tests for the template utils, to document
what we expect, and test that this works on all architectures.

The AST-based graph builder is by now only used for asm.js code. This
change hard-codes this assumption into the compilation pipeline and
hence allows us to remove support pertaining to deoptimization from
optimized code that was not derived from bytecode.

cb7dd0a911 Replace sanitizers:deps with exe_and_shlib_deps (v8)
All targets (at least on sanitizer builds) unconditionally depend
on //build/config/sanitizers:deps.

It is necessary for bug 593874 that all targets now also depend
on //buildtools/third_party/libc++:libcxx_proxy.  This requires
adding a new "global dependency": //build/config:exe_and_shlib_deps.

This CL updates references to sanitizers:deps to instead refer to
//build/config:exe_and_shlib_deps.

72019a0428 [wasm] Streaming decoder
This CL implements a streaming decoder which takes the bytes
of a wasm module as an input, potentially split into multiple
chunks, and decodes them into segments. Each segment either
contains the payload of a whole section, or the code of a
single function. The goal is that the streaming decoder is
used for streaming compilation. That's where the interface
comes from, see
(https://cs.chromium.org/chromium/src/v8/include/v8.h?q=OnBytesReceived&sq=package:chromium&l=4060)

Error positions are not reported correctly at the moment. I
plan to do this in a separate CL.

b7a7096668 [Interpreter] Remove BytecodePipeline.
The BytecodePipeline is no longer used by any optimizers, so remove it and
connect the BytecodeArrayBuilder directly to the BytecodeWriter.

Also remove some functions from BytecodeNode which are no longer used.

790b2d341c [Interpreter] Move dead code elimination to BytecodeArrayWriter.
Move dead bytecode elimination from a seperate bytecode pipeline optimizer
into the BytecodeArrayWriter. This removes the last bytecode pipeline
optimizer, which means we can remove the Bytecode pipeline which,
which should increase compile speed.
