This CL improves break locations for expressions like 'var a = <expr>'. Without CL we use <expr> position as break location for initialization statement, with this CL we use position of first character after '=' as position.
Benefits (see test for details):
 - only one break in expressions which includes mix of property lookup and calls, e.g. var p = Promise.resolve().then(x => x * 2),
 - removed redundant break location for expressions like: let { x, y } = { x: 1, y: 2}.

The problem with enums is that neither is_integral, nor is_signed or
is_unsigned is true for them. Thus, comparison with our CHECK/DCHECK
macros always just uses the default comparison, which fails if the
signedness of the underlying integer types does not match.
This CL fixes this by considering the underlying integer type of an
enum to choose the right comparison operator.

This CL replaces the last usages of std::vector in the AsmJsParser by
ZoneVector. This allows to also measure the memory consumption of these
vectors, since it is now contained in the zone memory.
ZoneVectors are reused to avoid accumulating lots of unused memory.

This also saves 2.6% performance (avg over 1000 runs) on my local
workstation.

Both lazy initialization and static initialization (via static
initializer) are bad. Fortunately, the arrays we are constructing are
constant anyway, so we can just compute them at compile time. This is
enforced by making them constexpr.
This also saves all code needed for the initialization, and makes
accesses to the tables faster, as they don't need any atomic operations
(via LazyInstance).

class StatsTable thead safe. This is needed because these two classes
call each other, and for background compilation, instances of the
Counters class can persist longer that the corresponding Isolate it

It also removes unnecessary hops to the the Isolate, and checks if the
