Fragmentation of LABs could result in increasing memory usage (pages) instead of shrinking.

Adds an evacuation mode that allows moving pages within new space without
copying objects.
Basic idea:
a) Move page within new space
b) Sweep page to make iterable and process ArrayBuffers
c) Finish sweep till next scavenge
Threshold is currently 70% live bytes, i.e., the same threshold we use
to determine fragmented pages.

The optimization stages in the bytecode generation pipeline must
preserve source position information. Failure to preserve
source position information could result in single stepping
in the debugger misbehaving or mis-reporting in exception stack traces.
This change adds tests intended to check optimizations do not damage
source position info.

Most maps have a small code cache (often only one entry), so this patch
optimizes memory consumption of such cases by using plain FixedArrays,
only switching to CodeCacheHashTables when the number of cached entries
gets so large that linear-scan lookups get too slow.
On loading inbox.google.com, this gets the aggregate size of all maps'
code caches (there are about 13,600 of them) from 4300 KB to 970 KB.

This patch does five things:
1. Extracts sampler as libsampler to provide sampling functionality support.
2. Makes SampleStack virtual so embedders can override the behaviour of sample collecting.
3. Removes sampler.[h|cc].
4. Moves sampling thread into log.cc as workaround to keep the --prof functionality.
5. Creates SamplerManager to manage the relationship between samplers and threads.
The reason we port hashmap.h is that in debug mode, STL containers are using
mutexes from a mutex pool, which may lead to deadlock when using asynchronously
signal handler.
Currently libsampler is used in V8 temporarily.

In order to have a wasm object (as JSObject), this adds a method to
instantiate the TestingModule. In order for this to work, the bytecode
and the function names of the TestingModule are stored for usage during
instantiation.

This prepares for pulling chromium's build as dependency for
gn. After this, the files in build and gypfiles need to stay
in sync until chromium is updated.

This will allow to pull in gyp as a deps to the same location
as chromium (tools/gyp not build/gyp), needed for gn switch.
This is the first step of a 3-way move.
1) Copy v8.gyp in v8
2) Update references in embedders (follow up)
3) Remove old v8.gyp (follow up)

This patch removes it entirely from the codebase.

We had exactly one test case for --noturbo-types, so it's likely that
the generic pipeline (without types) was already broken for quite some
time, plus no one expressed interest in maintaining it, plus it
complicates the JSGenericLowering integration. So decision is to kill
it.
