- change error message for `Object.create` invalid property descriptor
- disable v8 test cases for deprecated legacy RegExp static properties
and invalid left hand side error type
- update v8.txt
- fix v8.sh behavior for single tests
Translate IC opcodes to their non-IC variants before writing them out.
Before this commit they were not byte-swapped properly, breaking the
ability to load serialized bytecode containing ICs on systems with
different endianness. Inline caches are recomputed as needed now.
A pleasing side effect of this change is that serialized bytecode is,
on average, a little smaller because fewer atoms are duplicated now.
* 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
* Improve consistency of JS_NewFloat64 API
- `JS_NewFloat64()` always creates a `JS_TAG_FLOAT64` value
- internal `js_float64()` always creates a `JS_TAG_FLOAT64` value
- add `js_int64` internal function for consistency
- rename `float_is_int32` as `double_is_int32`
- handle `INT32_MIN` in `double_is_int32`, use (somewhat) faster alternative
- add `js_number(d)` to create a `JS_TAG_FLOAT64` or a `JS_TAG_INT` value
if possible
- add `JS_NewNumber()` API for the same purpose
- use non testing constructor for infinities in `js_atof2`
- always store internal time value as a float64
- merge `JS_NewBigInt64_1` into `JS_NewBigInt64`
- use comparisons instead of `(int32_t)` casts (implementation defined behavior)
* Improve string parsing and JSON parsing
- fix JSON parsing of non ASCII string contents
- more precise string parsing errors
- more precise JSON parsing errors
- add `JS_ParseState::buf_start` to compute line/column
- fix HTML comment detection at start of source code
- improve v8 Failure messages (pulled and modified `formatFailureText` from **mjsunit.js**)
- ignore more v8 tests
After much tinkering with libuv's CI, I finally figured out that ASLR
is the root cause for the ASan and MSan failures. Newer kernels use
bigger PIE slides and the sanitizer runtimes don't know how to handle
those (yet - looks like it's been fixed upstream.)

* 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)`
GitHub recently upgraded the ubuntu-latest images and I suspect that is
the cause of the linux-asan and linux-msan failures. Pin to the old LTS
for now.
Fixes: https://github.com/quickjs-ng/quickjs/issues/314
dlmalloc has been removed and the NDK now exposes a malloc.h header with
malloc_usable_size exposed, so use that.
Also remove the duplication in js__malloc_usable_size.

* 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**
* Fix bug in `GET_PREV_CHAR` macro
- pass `cbuf_type` variable to `XXX_CHAR` macros in `lre_exec_backtrack()`
- improve readability of these macros
- fix `GET_PREV_CHAR` macro: `cptr` was decremented twice on invalid high surrogate.
- minimize non functional changes
* Fix big endian serialization
Big endian serialization was broken because:
- it partially relied on `WORDS_ENDIAN` (unconditionally undef'd in cutils.h)
- endianness was not handled at all in the bc reader.
- `bc_tag_str` was missing the `"RegExp"` string
- `lre_byte_swap()` was broken for `REOP_range` and `REOP_range32`
Modifications:
- remove `WORDS_ENDIAN`
- use `bc_put_u32()` / `bc_put_u64()` in `JS_WriteBigInt()`
- use `bc_get_u32()` / `bc_get_u64()` in `JS_ReadBigInt()`
- handle host endianness in `bc_get_u16()`, `bc_get_u32()`, `bc_get_u64()` and
`JS_ReadFunctionBytecode()`
- handle optional littleEndian argument as specified in
`js_dataview_getValue()` and `js_dataview_setValue()`
- fix `bc_tag_str` and `lre_byte_swap()`
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.

- fix the conversions for integers and exact fractions
- approximate approach for other cases.
- bypass floating point conversions for JS_TAG_INT values
- avoid divisions for base 10 integer conversions
