* tic80-opc.c (tic80_operands): Add REG_0_E, REG_22_E,

	and REG_DEST_E for register operands that have to be
	an even numbered register.  Add REG_FPA for operands that
	are one of the floating point accumulator registers.
	Add TIC80_OPERAND_MASK to flags for ENDMASK operand.
	(tic80_opcodes): Change entries that need even numbered
	register operands to use the new operand table entries.
	Add "or" entries that are identical to "or.tt" entries.
