- improved tests/test_builtin.js `assert` function to compare
  values more reliably.
- added some tests in `test_date()`

bbf36d5b84 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.

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()`

3bb2ca360e Remove unnecessary ssize_t posix-ism
ssize_t is not always available and the cast it was used in wasn't
necessary in the first place, the value already has the right type.

Note that the field malloc_limit is an int64_t in JSMemoryUsage whereas it
is a size_t in JSMallocState.

  hacky test agains the length of fast_array object.
  This hack was removed by commit c3635861f6.
