* gdb.asm/asm-source.exp: Add "mips*-*" pattern. Update line

numbers.  Allow "foo2|selected stack frame".
        * gdb.asm/asmsrc1.s: Use gdbasm_declare and gdbasm_end.
        * gdb.asm/asmsrc2.s: Likewise.
        * gdb.asm/common.inc: Define gdbasm_declare and gdbasm_end.  Update
        comments.
        * gdb.asm/mips.inc: New file.
