Make -DDUMP_BYTECODE=64 print executed bytecode (#158)

699744562e Enable support for GCC compler v < 4.9 
GCCv4.8 and lower doesn't ship with stdatomic implementation
(even though they don't define __STD_NO_ATOMICS__ for c11).
If the code is compiled with GCCv4.8 and older, we use builtin
GCC atomic operations instead.

The patch was initially proposed in quickjs's mailing group:

Handle serialization endianness transparently (#152) 
Change JS_WriteObject() and JS_WriteObject2() to write little-endian
data and update JS_ReadObject() to byte-swap data when running on a
big-endian system.

Obsoletes the JS_WRITE_OBJ_BSWAP flag, it is now a no-op.

Implement static class initializer blocks (#144) 
Spec compliance bug: "await" is illegal inside initializer blocks
_except_ when used as an identifier in a function expression, like so:

    class C {
        static {
            var f = function await() {}
        }
    }

It is somewhat complicated to make the parser understand the distinction
and such code is probably rare or non-existent so I decided to leave
well enough alone for now.

Remove no-op OP_swap+OP_swap bytecode sequence (#143) 
Observed in generated code for static initializers. We could in theory
track and correct it in js_parse_class() but doing it as a peephole
optimization is both easier and more general.

Fix AsyncGenerator.prototype.return error handling (#109) 
A poisoned .constructor property is observable and the resulting

dropped, otherwise the generator hangs.

Fix uninitialized memory access (#68) 
An alternative fix is to zero the `values` and `count` fields in
JS_NewObjectFromShape() irrespective of the object's class_id but
handling it in JS_GetPropertyValue() feels cleaner.

Add fused get_loc0_loc1 opcode (#55) 
get_loc0 and get_loc1 are individually very frequent opcodes _and_ they
are very often paired together, making them ideal candidates for opcode
fusion.

Reduces microbench.js running time by about 4%.
