integer conversions:
- improve `u32toa_radix` and `u64toa_radix`, add `i32toa_radix`
- use `i32toa_radix` for small ints in `js_number_toString`
floating point conversions (`js_dtoa`):
- complete rewrite with fewer calls to `snprintf`
- remove `JS_DTOA_FORMAT`, define 4 possible modes for `js_dtoa`
- remove the radix argument in `js_dtoa`
- merge `js_dtoa1` into `js_dtoa`
- add `js_dtoa_infinite` for non finite values
- simplify sign handling
- handle locale specific decimal point transparently
helper function `js_fcvt`:
- simplify `js_fcvt`, remove `js_fcvt1`, reduce overhead
- round up manually instead of using `fesetround(FE_UPWARD)`.
helper function `js_ecvt`:
- document `js_ecvt` and `js_ecvt1` behavior
- avoid redundant `js_ecvt1` calls in `js_ecvt`
- fixed buffer contents, no buffer copies
- simplify decimal point handling
- round up manually instead of using `fesetround(FE_UPWARD)`.
miscellaneous:
- remove `CONFIG_PRINTF_RNDN`. This fixes some of the conversion errors
on Windows. Updated the tests accordingly
- this fixes a v8.sh bug on macOS: `0.5.toFixed(0)` used to produce `0` instead of `1`
- add regression tests, update test_conv unit tests
- add benchmarks for `toFixed`, `toPrecision` and `toExponential` number methods
- benchmarks show all conversions are now 40 to 45% faster (M2)
- fix radix conversion rounding code: incrementing the digit
does not work for '9'. We can assume ASCII so it works for
all other digits, especially all letters
- also avoid recomputing the string length
* Fix more error cases
- fix more cases of missing `sf->cur_pc`.
- use more precise error messages for number conversion methods
- add test cases in test_builtin.js
- updated v8 test results
* make `Object.prototype` an immutable prototype object
* throw an exception on `Object.setPrototypeOf(Object.prototype, xxx)`
* do not throw an exception for `Reflect.setPrototypeOf(Object.prototype, xxx)`
* Improve error handling
- throw RangeError for invalid string length
- throw RangeError for stack overflow with updated message
- fix case for `BigInt` error messages
- refine stack check for `next_token` and `json_next_token`
- throw SyntaxError for too many variables, arguments, parameters...
- v8.js: disable v8 specific tests
- v8.js: disable Realm object tests
- v8.js: disable MODULE tests
- v8.js: disable RegExp static properties tests
- use more precise error messages
- reorder property lookup in `js_obj_to_desc()` according to ECMA
- set global object's [Symbol.toStringTag] to "global"
- fix error message for duplicate parameter name in strict mode
* Improve `Date.parse()`
- rewrite `Date.parse()` with separate parsers
- return `NaN` for out of bounds field values as specified
- add `js_tzabbr` and `string_get_tzabbr` to handle timezone abbreviations
- improve `string_get_milliseconds` readability
- accept up to 9 decimals for millisecond fraction but truncate at 3
- accept many more alternative date/time formats
- add test cases in **tests/test_builtin.js**
- produce readable output for `Date` objects in repl
- use `JSON.stringify` to output `Date` and `string` values in **repl.js**
- remove `String.prototype.__quote`
- add `minimum_length` macro to specify argument array sizes (C99 except MSVC)
- v8.js: parse all environment variables and output them, update **v8.txt**
The non-Unicode version of the pattern was already accepted.
test262 tests it in an inverted sense in
test/built-ins/RegExp/unicode_restricted_identity_escape.js but
it appears to be per spec and both V8 and Spidermonkey accept it.

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.
