PR gas/11395
* config/tc-hppa.c (pa_ip): Set doubleword carry/borrow bit when a
doubleword completer or doubleword condition is found in an add/sub
instruction. Reject match for 'A'/'S' only if there is no condition
and d bit is not set.
* gas/hppa/basic/add2.s: Add test for a simple doubleword carry
instruction.
* gas/hppa/basic/sub2.s: Add tests for simple word and doubleword
borrow instructions.
* gas/hppa/basic/basic.exp: Update regexps for above.
* opcode/hppa.h: Clear "d" bit in "add" and "sub" patterns.
