    gregex: Allow G_REGEX_JAVASCRIPT_COMPAT in compile mask for g_regex_new
    
    The flag is still ignored but this way we properly deprecate
    at compile time without raising an unexpected criticals at runtime:
    
       g_regex_new: assertion '(compile_options & ~G_REGEX_COMPILE_MASK) == 0' failed
    
    and then failing to create the regex completely.
    
    Fixes 8d5a44dc8 ("replace pcre1 with pcre2")
