Handle TypedArray detach during iteration (#209)
Per spec: detaching the TA mid-iteration is allowed.

TypedArray.prototype.sort should not throw an exception when that
happens and now no longer does.

Don't throw OOB exception for detached typed array (#208)
`a[42] = 1` where a is a detached typed array should not throw but
`Object.defineProperty()` still should. Add a check and a flag that
distinguishes between the two cases.

Remove JSFunctionBytecode.has_debug flag (#207)
And merge the debug struct into JSFunctionBytecode because it is now

Record source column positions (#193)
And:
- display them in stack traces
- expose them as Function.prototype.columnNumber

OP_line_num is renamed to OP_source_loc and the pc2line data structure
is extended with the column number in zigzag encoding.

The bytecode version number BC_VERSION is incremented because pc2line
data is read and written by JS_ReadObject() and JS_WriteObject() when
it is present.

Handle TypedArray detach during iteration (#201)
Per spec: detaching the TA mid-iteration is allowed and should not
not throw an exception.

In the case of TypedArray.prototype.set, because iteration over the
source array is observable, we cannot bail out early when the TA is
first detached.

Replace JSValueConst with JSValue (#195)
JSValueConst was only used for the now removed CONFIG_CHECK_JSVALUE
build mode. It is kept around as an alias for JSValue in quickjs.h to
avoid breaking everyone's source builds but remove it everywhere else.

Fix OP_FMT_none_loc bytecode dumping (#192)

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.

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.

Fix use-after-free on error during module evaluation
E.g. if during evaluation of module A, we start loading module B and
an error occurs. This results in a call to js_free_modules() with
JS_FREE_MODULE_NOT_EVALUATED, and since module A isn't yet evaluated,
it gets freed prematurely.

To solve this we improve js_free_modules() to ensure `eval_mark` is not
set. Once js_evaluate_module() returns for module A, it will notice that
an exception occurred and call js_free_modules() with
JS_FREE_MODULE_NOT_EVALUATED. Since `eval_mark` has been cleared by then,
module A gets cleaned up as well.
