Hi!
The documentation and intent as well as asm_operand_ok implement either
< or > allowing side-effects, while constrain_operands mistakenly
implemented requirement that both < and > are present for that.
Fixed thusly, committed as obvious.

* recog.c (constrain_operands): Allow side-effects in memory
operands if either < or > constraint is used, rather than if
both < and > is used.
