Implement RegExp 'v' flag, part 1 (#229) 
This commit implements the flag itself and teaches the regex engine to

Handle negative zero typed array indices correctly (#212) 
`ta["-0"] = 42` is a thing and not just any thing but a decidedly weird

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)

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.
