This revision adds support in the parser/printer for "deferrable" aliases, i.e. those that can be resolved after printing has finished. This allows for printing aliases for operation locations after the module instead of before, i.e. this is now supported:
```
"foo.op"() : () -> () loc(#loc)
#loc = loc("some_location")
```

Locations often get very long and clutter up operations when printed inline with them. This revision adds support for using aliases with trailing operation locations, and makes printing with aliases the default behavior. Aliases in the trailing location take the form `loc(<alias>)`, such as `loc(#loc0)`. As with all aliases, using `mlir-print-local-scope` can be used to disable them and get the inline behavior.

Summary: The current syntax for AffineMapAttr and IntegerSetAttr conflict with function types, making it currently impossible to round-trip function types(and e.g. FuncOp) in the IR. This revision changes the syntax for the attributes by wrapping them in a keyword. AffineMapAttr is wrapped with `affine_map<>` and IntegerSetAttr is wrapped with `affine_set<>`.

This is an important step in allowing for the top-level of the IR to be extensible. FuncOp and ModuleOp contain all of the necessary functionality, while using the existing operation infrastructure. As an interim step, many of the usages of Function and Module, including the name, will remain the same. In the future, many of these will be relaxed to allow for many different types of top-level operations to co-exist.

Example inline notation:
trailing-location ::= 'loc' '(' location ')'
// FileLineCol Location.
%1 = "foo"() : () -> i1 loc("mysource.cc":10:8)
// Name Location
return loc("foo")
// CallSite Location
return loc(callsite("foo" at "mysource.cc":19:9))
// Fused Location
/// Without metadata
func @inline_notation() loc(fused["foo", "mysource.cc":10:8])
/// With metadata
return loc(fused<"myPass">["foo", "foo2"])
// Unknown location.
return loc(unknown)
Locations are currently only printed with inline notation at the line of each instruction. Further work is needed to allow for reference notation, e.g:
...
return loc 1
}
...
loc 1 = "source.cc":10:1
