  New Revision: 58491

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=58491

  Log:
    load.c: make fstrings from C strings sooner
    
    The underlying string objects will become fstrings anyways,
    so create the fstring directly from the C string to reduce
    intermediate garbage.
    
    * load.c (rb_provide, rb_provide): create fstring
