This constraint can be used to limit a SymbolRefAttr to point
to a specific kind of op in the closest parent with a symbol table.

This CL adds a new FloatElementsAttr definition to ODS for float
elements attributes of a certain type.
Tests are added to show both verification and how to use it in patterns.

This commit adds `PositiveI32Attr` and `PositiveI64Attr` to match positive
integers but not zero nor negative integers. This commit also adds
`HasAnyRankOfPred` to match tensors with the specified ranks.

In ODS, right now we use StringAttrs to emulate enum attributes. It is
suboptimal if the op actually can and wants to store the enum as a
single integer value; we are paying extra cost on storing and comparing
the attribute value.
This CL introduces a new enum attribute subclass that are backed by
IntegerAttr. The downside with IntegerAttr-backed enum attributes is
that the assembly form now uses integer values, which is less obvious
than the StringAttr-backed ones. However, that can be remedied by
defining custom assembly form with the help of the conversion utility
functions generated via EnumsGen.
Choices are given to the dialect writers to decide which one to use for
their enum attributes.

The current syntax separates the name and value with ':', but ':' is already overloaded by several other things(e.g. trailing types). This makes the syntax difficult to parse in some situtations:
Old:
"foo: 10 : i32"
New:
"foo = 10 : i32"

This name has caused some confusion because it suggests that it's running op verification (and that this verification isn't getting run by default).
