Introduce and use operation::type_p

There's currently code in gdb that checks if an expression evaluates
to a type.  In some spots this is done by comparing the opcode against
OP_TYPE, but other spots more correctly also compare with OP_TYPEOF
and OP_DECLTYPE.

This patch cleans up this area, replacing opcode-checking with a new
method on 'operation'.

Generally, checking the opcode should be considered deprecated,
although it's unfortunately difficult to get rid of opcodes entirely.

I also took advantage of this change to turn eval_op_type into a
method, removing a bit of indirection.
