[PTX] remove unnecessary predicates

- Authentication-results: sourceware.org; auth=none
I've committed this patch to remove some unused or unnecessary operand
predicates. The address-space predicates are not used anywhere. The
const_0_operand is one small typo away from const0_operand. And as it turns out
unnecessary for its only use in a define_expand for ctrap. const0_operand is the
right predicate there anyway.

* config/nvptx/nvptx.md (const_0_operand, global_mem_operand,
const_mem_operand, param_mem_operand, shared_mem_operand): Delete.
(ctrap<mode>): Use const0_operand.
