Fixed CMakeLists.txt for Emscripten builds (#403)
Prevent compilation of __run-test262__  for Emscripten (fails due to the `ftw()` usage, but not needed anyway).

Improve internal string allocation methods (#398)
String values are allocated as temporary or final results. This commit
attempts to improve the consistency and performance of this step.

- define `JS_NewString` as an inline function to allow simple expansion
  of `strlen()` for string literals
- document string contents constraints regarding UTF-8 encoding.
- rename `js_new_string8` as `js_new_string8_len`. takes `const char *`.
- new inline function `js_new_string8` takes `const char *`, computes
  string length with `strlen` and calls `js_new_string8_len`. No overhead
  for string literals
- rename `js_new_string16` to `js_new_string16_len`
- use internal string allocation functions where appropriate, remove overhead
- allocate extra byte for null terminator in source code string

Fix encoding bug in js_dtoa_radix (#399)
- 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

Add utility functions for string to integer conversions (#366)
* Add utility functions, improve integer conversion functions

- move `is_be()` to cutils.h
- add `is_upper_ascii()` and `to_upper_ascii()`
- add extensive benchmark for integer conversion variants in **tests/test_conv.c**
- add `u32toa()`, `i32toa()`, `u64toa()`, `i64toa()` based on register shift variant
- add  `u32toa_radix()`, `u64toa_radix()`, `i64toa_radix()` based on length_loop variant
- use direct converters instead of `snprintf()`
- copy NaN and Infinity directly in `js_dtoa1()`
- optimize `js_number_toString()` for small integers
- use `JS_NewStringLen()` instead of `JS_NewString()` when possible
- add more precise conversion tests in microbench.js
- disable some benchmark tests for gcc (they cause ASAN failures)

- `-ss` strips source and line/column numbers information
- `qjsc repl.js` generates an object size of **105726** bytes
- `qjsc -s repl.js` generates an object size of **20853** bytes
- `qjsc -ss repl.js` generates an object size of only **16147** bytes
- compile repl.js with `-ss`
- bump byte code version to 12

Fix member accesses for non-decimal numeric literals (#377)
* Fix member accesses for non-decimal numeric literals
    e.g. 0x0.a should return undefined, not SyntaxError.
* Remove ineffective non-decimal float parsing code and redundant checks on `is_float && radix != 10`
    (The code already wasn't doing anything because of the `is_float` check.)

* Expose public equality comparison and sameness public API.
- add `JS_IsEqual` (operator `==`), returns an `int`: `-1` if an exception was thrown
- add `JS_IsStrictEqual` (operator `===`) always succeeds, returns a `JS_BOOL`
- add `JS_IsSameValue` always succeeds, returns a `JS_BOOL`
- add `JS_IsSameValueZero` always succeeds, returns a `JS_BOOL`

Improve dump option support (#344)

    dump options, generalize command line option handling
- improve DUMP_READ_OBJECT output, fix indentation issue

38fa7d7cf6 Fix crash in FinalizationRegistry when the observed object is GC'd
In the pathological case shown in
https://github.com/quickjs-ng/quickjs/issues/367 both the object and the
registry will be destroyed as part of the GC phase of JS_FreeRuntime.
When the GC sweep happens it's possible we are holding on to a corpse so
avoid calling the registry callback in that case.

This is similar to how Weak{Map,Set} deal with iterators being freed as
part of a cycle.

Remove js_unlikely macro (#370)
It was a wrapper around gcc's __builtin_expect macro but it was only
used in three places and not in a way that suggests it really helps
branch prediction on modern (or even not so modern) CPUs.
