      Now Char, Char#, StgChar have 31 bits (physically 32).
      "foo"# is still an array of bytes.
      
      CharRep represents 32 bits (on a 64-bit arch too). There is also
      Int8Rep, used in those places where bytes were originally meant.
      readCharArray, indexCharOffAddr etc. still use bytes. Storable and
      {I,M}Array use wide Chars.
      
      In future perhaps all sized integers should be primitive types. Then
      some usages of indexing primops scattered through the code could
      be changed to then-available Int8 ones, and then Char variants of
      primops could be made wide (other usages that handle text should use
      conversion that will be provided later).
      
      I/O and _ccall_ arguments assume ISO-8859-1. UTF-8 is internally used
      for string literals (only).
      
      Z-encoding is ready for Unicode identifiers.
      
      Ranges of intlike and charlike closures are more easily configurable.
      
      I've probably broken nativeGen/MachCode.lhs:chrCode for Alpha but I
      don't know the Alpha assembler to fix it (what is zapnot?). Generally
      I'm not sure if I've done the NCG changes right.
      
      This commit breaks the binary compatibility (of course).
      
      TODO:
      * is* and to{Lower,Upper} in Char (in progress).
      * Libraries for text conversion (in design / experiments),
        to be plugged to I/O and a higher level foreign library.
      * PackedString.
      * StringBuffer and accepting source in encodings other than ISO-8859-1.
