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.

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

A std::deque interacts badly with zone memory in that it allocates chunks
of memory for the back of the queue and frees memory from the front of the
queue. As such we never reuse zone memory for the queue. Implement a very
simple RecyclingZoneAllocator which keeps a single block of memory from
deallocation that can be reused on allocation.
Also clean up zone-allocator a bit and make it use proper Chromium coding
style.

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.

types (lists themselves also zone-allocated):

This change makes the architecture that we target generated
v8 code for a property of the current toolchain, rather than a
global setting that applies to every toolchain.
This will allow us to properly build two snapshots for two different
architectures in a single build, which is needed for android
webview/monochrome builds.

This avoids forgetting to add files for either gyp or gn.
While for most executables, this is detected by compilation
errors, for test executables, it can lead to tests silently
not running.

Those were wrongly translated from gyp with ia32. This should
land before renaming v8_target_arch to v8_target_cpu.

This moves common configs used by all v8 targets into
common templates.
This also fixes using v8_optimized_debug correctly in
executables and components.

We were able to achieve our goals for register allocation independent of
the allocation algorithm. Performance data so far is inconclusive re. the
value of the Greedy algorithm, compared to the particular Linear Scan
implementation we're currently using, and the performance measurement
techniques we currently use are too imprecise to help with this matter.
Retiring the algorithm to lower maintenance and evolution cost (e.g. lower
cost of adding aliasing support). Once we improve benchmarking stability,
and establish a suite sensitive enough for codegen improvement studies,
we may revive the algorithm, should the need arise.

VC++ complains about truncation of integer constants despite use of
static_cast. This isn't very helpful as it gives no way of suppressing
the warning in code, so this change suppresses it on the command line.
Additionally, the linker complains about importing of locally defined
functions in component builds. Until this is fixed the warnings should
be suppressed.
