Now roll_merge_gerrit.py waits for a +1, and immediately submits. With
auto-submit and rubber-stamper bot, this makes the script fully
fire-and-forget.
This also fixes the commit message update to include the change id.

Namely:
- AccessorInfo::getter and AccessorInfo::js_getter,
- CallHandlerInfo::callback and CallHandlerInfo::js_callback.
The redirected/non-redirected callback distinction is required only
for simulated builds but we wasted memory also for all native builds.
Now we store these fields in "redirected" form which allows us to call
them directly from builtins or generated code. In case it's necessary
to call a callback from C++ code the C function address is read from
the redirection. This additional indirection makes the callback calls
from C++ code in simulated builds slower but saves memory for native
builds.
This CL should recover a part of memory regression caused by inlining
Foreign fields into AccessorInfo and CallHandlerInfo.

This CL changes the WasmTypeInfo class to have a direct ExternalPointer
to the native type structure instead of using a Foreign. This in turn
makes it possible to use a unique pointer tag for that external pointer
when the sandbox is enabled.

The system analyzer relies on server-side processing to symbolize C++
addresses, using lws-middleware.js:
ws --stack system-analyzer/lws-middleware.js lws-static cors
This does not work on Android however, given the log file refers to the
stripped apk file rather than the unstripped libchrome.so binary. This
CL adds the --apk-embedded-library option to the middleware script to
make this work:
ws --stack system-analyzer/lws-middleware.js lws-static cors \
--apk-embedded-library=/path/to/out/android/lib.unstripped/libchrome.so
Also, for completeness, add the --target option to set targetRootFS.

Add flag contradictions for "assert-types" flag and a README file for how
to add trials from the source side. Also restore "assert-types" and its
contradictions' probability since we can avoid contradictions now.

This is a reland of commit 07e11a64e4.
The original change removed the fill_thehole_and_call_runtime bailout
in StringBuiltinsAssembler::StringToArray() so when the string
is external and cannot be unpacked, the FixedArray won't be filled
with holes before we call into the runtime, thus failing a
heap verification if a GC happens before the array is filled. This
reland adds back the bailout for this case.
Bug: v8:12718, chromium:1330410
Original change's description:
> [heap] pre-populate the single_character_string_cache
>
> This simplifies the code and removes the runtime overhead of
> spontaneously adding strings to the cache.
