* 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`
- DUMP_XXX defined as nothing or 0 produces unconditional output
- DUMP_XXX defined as a bitmask produces conditional output based
on command line option -d<bitmask>
- add `JS_SetDumpFlags()` to select active dump options
- accept -d[<hex mask>] and --dump[=<hex mask>] to specify active
dump options, generalize command line option handling
- improve DUMP_READ_OBJECT output, fix indentation issue
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.
Fixes: https://github.com/quickjs-ng/quickjs/issues/367
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.

- avoid crashing on invalid atoms in `JS_AtomGetStrRT`
- do not dump objects and function_bytecode during
`JS_GC_PHASE_REMOVE_CYCLES` phase
- fix crash in `print_lines` on null source
* Improve REPL directive support
- use . on column 0 as directive prefix
- use `directives` object properties for genericity
- accept non ambiguous directive abbreviations
- reject invalid directive with extra characters
- simplify `handle_directive` and `handle_cmd`
- document ".help" instead of "\h"
- document ".load"
CMAKE_BUILD_TYPE only applies on single-configuration generators: https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html
For multi-configuration generators like Visual Studio (or Xcode) --config needs to be used in order to build that specific configuration.
* Improve completion in REPL
- refine `get_context_object` to avoid throwing errors (eg: q.<TAB>)
- do not call `eval` in `get_context_object` to avoid throwing errors
and reduce bloat caused by variable closures.
- support completion of directives
* Optimize `JS_GetPropertyInt64` and `JS_TryGetPropertyInt64`
- add `js_get_fast_array_element()` to special case arrays and typed arrays
- use `js_get_fast_array_element()` in `JS_GetPropertyValue()`,
`JS_TryGetPropertyInt64()` and `JS_GetPropertyInt64()`.
- simplify `js_array_at()`
- 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
