Replace `IntrinsicEmitter::ComputeFixedEncoding()` and cleanup

[chapuni]

Summary

Depends on D146915

[chapuni]

• Update (w/ some fixups)

Does this mean it's now possible to define codegen patterns that accept different types? e.g. a single store pattern that accepts i32 and f32 inputs?

[chapuni]

Rebase on D143844

[chapuni]

Restore the last cleanup

I suppose this is just a convention for coming MVTEmitter to emit MVT::isOverloaded(). I have no idea if we could enhance semantics.

 Note that all of the values have rules for converting them from one type to
 another. For example, these rules allow you to assign a value like ``7``
 to an entity of type ``bits<4>``.
 
 .. productionlist::
    Value: `SimpleValue` `ValueSuffix`*
         :| `Value` "#" [`Value`]
    ValueSuffix: "{" `RangeList` "}"
-              :| "[" `RangeList` "]"
+              :| "[" `SliceElements` "]"
               :| "." `TokIdentifier`
    RangeList: `RangePiece` ("," `RangePiece`)*
    RangePiece: `TokInteger`
              :| `TokInteger` "..." `TokInteger`
              :| `TokInteger` "-" `TokInteger`
              :| `TokInteger` `TokInteger`
+   SliceElements: (`SliceElement` ",")* `SliceElement` ","?
+   SliceElement: `Value`
+               :| `Value` "..." `Value`
+               :| `Value` "-" `Value`
+               :| `Value` `TokInteger`(negative)
 
 .. warning::
   The peculiar last form of :token:`RangePiece` is due to the fact that the
   "``-``" is included in the :token:`TokInteger`, hence ``1-5`` gets lexed as
   two consecutive tokens, with values ``1`` and ``-5``, instead of "1", "-",
   and "5". The use of hyphen as the range punctuation is deprecated.
 
 Simple values

 
 *value*\ ``{17}``
     The final value is bit 17 of the integer *value* (note the braces).
 
 *value*\ ``{8...15}``
     The final value is bits 8--15 of the integer *value*. The order of the
     bits can be reversed by specifying ``{15...8}``.
 
-*value*\ ``[4]``
-    The final value is element 4 of the list *value* (note the brackets).
+*value*\ ``[i]``
+    The final value is element `i` of the list *value* (note the brackets).
     In other words, the brackets act as a subscripting operator on the list.
     This is the case only when a single element is specified.
 
+*value*\ ``[i,]``
+    The final value is a list that contains a single element `i` of the list.
+    In short, a list slice with a single element.
+
 *value*\ ``[4...7,17,2...3,4]``
     The final value is a new list that is a slice of the list *value*.
     The new list contains elements 4, 5, 6, 7, 17, 2, 3, and 4.
     Elements may be included multiple times and in any order. This is the result
     only when more than one element is specified.
 
+    *value*\ ``[i,m...n,j,ls]``
+        Each element may be an expression (variables, bang operators).
+  The type of `m` and `n` should be `int`.
+  The tyep of `i`, `j`, and `ls` should be either `int` or `list<int>`.
+
 *value*\ ``.``\ *field*
     The final value is the value of the specified *field* in the specified
     record *value*.
 
 The paste operator
 ------------------
 
 The paste operator (``#``) is the only infix operator available in TableGen
``!not(``\ *a*\ ``)``
     an integer. The argument 0 results in 1 (true); any other
     argument results in 0 (false).
 
 ``!or(``\ *a*\ ``,`` *b*\ ``, ...)``
     This operator does a bitwise OR on *a*, *b*, etc., and produces the
     result. A logical OR can be performed if all the arguments are either
     0 or 1.
 
+``!range([``\ *a*\ ``,``] *b*\ ``)``
+    This operator produces half-open range sequence ``[a : b)`` as ``list<int>``.
+    *a* is ``0`` by default. ``!range(4)`` is equivalent to ``!range(0, 4)``.
+    Its result is `[0, 1, 2, 3]`.
+    The result is `[]<list<int>>` if *a* ``>=`` *b*.
+
+``!range([``\ *list*\ ``)``
+    Equivalent to ``!range(0, !size(list))``.
+
 ``!setdagop(``\ *dag*\ ``,`` *op*\ ``)``
     This operator produces a DAG node with the same arguments as *dag*, but with its
     operator replaced with *op*.
 
     Example: ``!setdagop((foo 1, 2), bar)`` results in ``(bar 1, 2)``.
 
 ``!shl(``\ *a*\ ``,`` *count*\ ``)``
     This operator shifts *a* left logically by *count* bits and produces the resulting
