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)

Use more functions for explicit surrogate handling (#353)

473bd1d531 Fix Android build
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 Date.parse (#289)
* 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 big endian serialization (#269)
* 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()`

Fix tcc build, remove PACK macro (#271)
There was no definition of the macro for compilers that were not gcc,
clang or msvc. While it would be easy to add one, a better approach is
to switch to memcpy() and avoid type punning altogether.

bfd8c381cb Add support for building with ClangCL on Windows
Since ClangCL is compatible with MSVC this should get us almost there.

Remove trailing whitespace (#46)
Not purely cosmetic because it breaks navigation with { and } in the
