Improve handling of REPT pseudo op with a negative count.
PR 22324
* read.c (s_rept): Use size_t type for count parameter.
(do_repeat): Change type of count parameter to size_t.
Issue an error is the count parameter is negative.
(do_repeat_with_expression): Likewise.
* read.h: Update prototypes for do_repeat and
do_repeat_with_expression.
* doc/as.texinfo (Rept): Document that a zero count is allowed but
negative counts are not.
* config/tc-rx.c (rx_rept): Use size_t type for count parameter.
* config/tc-tic54x.c (tic54x_loop): Cast count parameter to size_t
type.
* testsuite/gas/macros/end.s: Add a test using a negative repeat
count.
* testsuite/gas/macros/end.l: Add expected error message.
