Creates a new class StatsCounterThreadSafe to be used by counters that
can be updated when compiling/decoding etc. are done using workers.

Does this by using a mutex on all opreations.

Also updates the StatsCounterThreadSafe constructor to force counter
initialization, as well as method Reset(). In addition, whenever the
method StatsTable::SetCounterFunction() is called (from the main
thread), it forces counter initialization for all thread safe stats
counters.

Rather than trying to pre-calculate the number of contexts required during
scope analysis, instead just allocate context registers in the register
allocator. This reduces frame size a bit due to reusing of registers when
the context isn't pushed.

In particular, local variables should be allocated on stack (in bytecode register), and stored/loaded to the generator object on generator suspend/resume.

The CL is based on @adamk's change to scoping/parsers (https://chromium-review.googlesource.com/c/498538/), I only made the debugger cope with this change.

I should note that the CL changes the scope type of suspended generators from ScopeType.Closure to ScopeType.Local. In the future we might want to introduce ScopeType.SuspendedGenerator to make the distinction explicit.

Some of the changes in the tests have been made because the debugger functions do not return scopes of closed generators anymore. Generators should be allowed to throw away their internal state when they finish.

This removes the need for certain context scopes to skip popping the
context register. For the {incoming_context} the flag was already
obsolete, because its destructor would only run once the basic block
ended with a return. For {local_function_context} the same holds now
by moving handling of implicit returns into the body visitor.

There are two break locations at the same source location by desugaring:
- call iterator.next,
- before variable assignment.

Additionally location for for..of loops is moved from before "of" to before each variable expression.

We should not report first implicit call to avoid user confusion. User still able to go into .next function with both scenarios:
- when this call is reached by stepOver or stepInto from previous line,
- when this call is reached because of breakpoint at current line.

This avoids emitting redundant {PopContext} bytecode instructions when
non-local control-flow leaves the method body. It also folds multiple
such {PopContext} instructions into one, in case several scoping levels
are crossed at one. Only the expected context of the target of a local
control-flow transfer matters.

Before emitting the safepoint table, remove consecutive identical
entries (idential except for the pc of course). The lookup then
searches for the last entry whose pc is <= the wanted pc.
The lookup procedure can still be optimized to use binary search
laster.

This change decreases code size for wasm by 27.6% (on the unity
benchmark).
