    Normalize Latin-1 characters in `String#normalize("NFKC")``
    https://bugs.webkit.org/show_bug.cgi?id=269783

    Reviewed by Alexey Proskuryakov.

    The `String.prototype.normalize` implementation has a fast-path in
    cases where normalization does not affect the string. It was incorrectly
    assumed that NFKC does not affect 8-bit strings. The only normalization
    that doesn't affect them is NFC.

    [JSC] Add missed "cc" inline asm clobber to ARM64 memory operations
    https://bugs.webkit.org/show_bug.cgi?id=269785

    Reviewed by Keith Miller.

    Since inline asm touches flags, it should set "cc" clobber to ensure
    a compiler will schedule instructions correctly.

    W/o the clobber and if compiled with clang v16 and newer (AArch64,
    Linux) may lead to a crash inside JSArray::unshiftCountSlowCase().
