* genopinit.c: Use $ for escape sequences in optab patterns.
	Remove backslashes from optab patterns.  Change $A, $B, $C to
	expand to (int) whatever instead of just whatever; remove
	explicit (int) from all optab patterns.

This array contains a list of optabs that need to be initialized. Within
each string, the name of the pattern to be matched against is delimited
with %( and %). In the string, %a and %b are used to match a short mode
with $( and $). In the string, $a and $b are used to match a short mode
name (the part of the mode name not including `mode' and converted to
lower-case). When writing out the initializer, the entire string is
used. %A and %B are replaced with the full name of the mode; %a and %b
used. $A and $B are replaced with the full name of the mode; $a and $b
are replaced with the short form of the name, as above.
If %N is present in the pattern, it means the two modes must be consecutive
widths in the same mode class (e.g, QImode and HImode). %I means that
only integer modes should be considered for the next mode, and %F means
If $N is present in the pattern, it means the two modes must be consecutive
widths in the same mode class (e.g, QImode and HImode). $I means that
only integer modes should be considered for the next mode, and $F means
that only float modes should be considered.
For some optabs, we store the operation by RTL codes. These are only
used for comparisons. In that case, %c and %C are the lower-case and
used for comparisons. In that case, $c and $C are the lower-case and
upper-case forms of the comparison, respectively. */
