It turned out that on arm and arm64 we over-estimated the code size of a
Wasm module quite a bit. This CL adds some more output for the
--trace-wasm-compilation-times flag, and adds a script to compute the
factors we use for code size estimates from that output.
I ran the script on a few benchmarks (an older Epic module, the current
Photoshop module, and the benchmark from the linked bug), and adjusted
the constants accordingly.

Also, simplify the API of {ReservationSize} to only return a single
number, and fail internally if we need to allocate more than the engine
supports (which would only fail for artificially large modules).

This CL moves the call to GCTracer::StopCycle for the full GC from
Heap::CompleteSweeping full, which is called to force sweeping to
finish, to GCTracer::NotifySweepingComplete, which is called as soon
as sweeping finishes --- and symmetrically to a new method
GCTracer::NotifyCppGCCompleted, which is called as soon as sweeping
of the managed C++ heap finishes. In this way, a full GC cycle is
reported as soon as sweeping is finished both for the V8 and the C++
managed heap.

The changes introduced in this CL are essentially a partial revert of
https://crrev.com/c/3456563, fixed in such a way that when the full
GC cycle is reported, the current tracer event will be the correct
one corresponding to that cycle.

Running `OS::AllocatePageSize()` on PPC simulator (which
runs on x64 Linux) will make a `sysconf(_SC_PAGESIZE)` call
which returns the native x64 Linux page size and not the PPC
specific page size.

This can cause a problem if used along side the current value of
`kPageSizeBits` which is set to use PPC value even on Sim.
As an example a newly added DHCECK under https://crrev.com/c/3497363
was failing on PPC Sim as a call to `AllocatableMemoryInDataPage`
was being made which used kPageSizeBits on Sim.

Meanwhile another function was using the `page_size_bits` value which
gets set by _SC_PAGESIZE. The mismatch caused an incorrect final value
being generated which failed the DCHECK.

Modernise the RegList interface to be a proper class, rather than a
typedef to an integer, and add proper methods onto it rather than ad-hoc
bit manipulation.

In particular, this makes RegList typesafe, adding a DoubleRegList for
DoubleRegisters.

The Arm64 CPURegList isn't updated to use (or extend) the new RegList
interface, because of its weird type-erasing semantics (it can store
Registers and VRegisters). Maybe in the future we'll want to get rid of
CPURegList entirely and use RegList/DoubleRegList directly.
