Switch all uses of NewCode and TryNewCode to CodeBuilder and remove these
methods.
NewCode and TryNewCode use a large number of default parameters, which makes
it difficult to use and add any new ones. Large chunks of code were also
duplicated across TryNewCode and NewCode. The previous CL
(https://chromium-review.googlesource.com/c/v8/v8/+/1585736) added a new
CodeBuilder class which allows much simpler building of Code objects.

LockGuard is mostly used with Mutex. Since both are defined outside the
internal namespace, we often have to write
{base::LockGuard<base::Mutex>}. This CL shortens this to
{base::MutexGuard} across the code base

There is no good reason to have the meat of most objects' initialization
logic in heap.cc, all wrapped by the CALL_HEAP_FUNCTION macro. Instead,
this CL changes the protocol between Heap and Factory to be AllocateRaw,
and all object initialization work after (possibly retried) successful
raw allocation happens in the Factory.
This saves about 20KB of binary size on x64.

In order to remove the CALL_GENERATED_CODE macro, it helps a lot to
unify the interfaces of the simulators and make the Call method variadic
in the number of arguments.
This CL does that for each simulator. A follow-up CL will then
completely remove the CALL_GENERATED_CODE macro and replace uses with
the (new) GeneratedCode wrapper.

Some tests were recently added to test-simulator-arm.cc, however this file is
meant for tests that are specific to the simulator and therefore are not written
to work on hardware. While this sounds surprising, the reason is that our simulation
of synchronisation instructions is more conservative than on hardware.
To make this more clear, this patch renames the "test-simulator-arm{,64}.cc"
files to "test-sync-primitives-arm{,64}.cc", and moves the vneg and vabs tests
into "test-assembler-arm.cc" which is were tests that are garanteed to work in
either native or simulated environments live.
Finally, take the opportunity to share a little bit of code.
