Use alternative_mask for add_insn_allocno_copies
add_insn_allocno_copies and its subroutines used HARD_REG_SET to
represent a bitmask of alternatives. There's not really any connection
between the number of registers and the maximum number of alternatives,
so this patch uses alternative_mask instead (which wasn't around when
this code was added).
This is just a minor clean-up making way for later patches.

gcc/
* ira-int.h (ira_setup_alts, ira_get_dup_out_num): Use
alternative_mask instead of HARD_REG_SET to represent a
bitmask of alternatives.
* ira.c (ira_setup_alts, ira_get_dup_out_num): Likewise.
* ira-conflicts.c (add_insn_allocno_copies): Likewise.
