[SystemZ] Add support for .insn and .word/.short/.long/.quad directives

Add support for these directives to allow inline asm and the integrated
assembler to understand them and to properly emit them.

.insn is an s390 specific directive that allows encoding of an instruction
instead of using a mnemonic. The motivating case is some code in node.js that
requires support for the .insn and .word directives.
