They are often labeled just "integer" currently.  Fix that.

Also handle shift properly in those scheduling descriptions that
neglected it.

From-SVN: r210873

They are currently just "integer", but the dot version is fast_compare.
This makes them all "logical".

From-SVN: r210872

They are currently just "integer", but the dot version is fast_compare.
This makes them all "add".  Later we should introduce attributes to
distinguish e.g. addc and adde (which aren't currently handled as
separate instructions at all, only in groups).

From-SVN: r210871

This uses the attributes "var_shift" and "dot" to specify the differences:

	var_shift_rotate    -> shift var_shift=yes
	delayed_compare     -> shift var_shift=no  dot=yes
	var_delayed_compare -> shift var_shift=yes dot=yes

From-SVN: r210870

This uses the attribute "size" to specify the differences:

	idiv -> div size=32
	ldiv -> div size=64

It could use "dot" as well, but the current code doesn't handle that.

From-SVN: r210869

This uses the attribute "size" to specify the differences:

	insert_word  -> insert size=32
	insert_dword -> insert size=64

It could use "dot" as well, but the current code doesn't handle that.

From-SVN: r210868

This uses the attributes "size" and "dot" to specify the differences:

	imul3 -> mul size=8
	imul2 -> mul size=16
	imul -> mul size=32
	lmul -> mul size=64
	imul_compare -> mul size=32 dot=yes
	lmul_compare -> mul size=64 dot=yes

From-SVN: r210867

This is for the legacy integer multiply-accumulate instructions.
Quite a mouthful, and "mulhw" is also a terrible name since we already
have a machine instruction called exactly that.  Hence "halfmul".

Also fixes the titan automaton description for this.

From-SVN: r210866

Get rid of the one huge line.  Group and order things a bit.  Further
changes will follow so this doesn't try to make it perfect.
