cgen patch for MAX_OPERANDS > 128 : CGEN_SYNTAX_CHAR_TYPE

[Patrick Macdonald <patrickm@redhat.com>]

Hello,

This is a small patch for the MAX_OPERANDS > 128 : CGEN_SYNTAX_CHAR_TYPE 
problem.  CGEN_SYNTAX_CHAR_TYPE will now be typedef'd to an unsigned
short regardless of MAX_OPERAND.    

Also, renamed CGEN_MAX_SYNTAX_BYTES to CGEN_MAX_SYNTAX_ELEMENTS to
correctly describe the current logic/definitions and modified the
existing ports that used CGEN_MAX_SYNTAX_BYTES.

Any questions or problems?
 
Patrick
