* Optionally attach the type of integer and floating point attributes to the attributes, this allows restricting a int/float to specific width.
- Currently this allows suffixing int/float constant with type [this might be revised in future].
- Default to i64 and f32 if not specified.
* For index types the APInt width used is 64.
* Change callers to request a specific attribute type.
* Store iN type with APInt of width N.
* This change does not handle the folding of constants of different types (e.g., doing int type promotions to support constant folding i3 and i32), and instead restricts the constant folding to only operate on the same types.

Array attributes can nested and function attributes can appear anywhere at that
level. They should be remapped to point to the generated CFGFunction after
ML-to-CFG conversion, similarly to plain function attributes. Extract the
nested attribute remapping functionality from the Parser to Utils. Extract out
the remapping function for individual Functions from the module remapping
function. Use these new functions in the ML-to-CFG conversion pass and in the
parser.

Change the storage type to APInt from int64_t for IntegerAttr (following the change to APFloat storage in FloatAttr). Effectively a direct change from int64_t to 64-bit APInt throughout (the bitwidth hardcoded). This change also adds a getInt convenience method to IntegerAttr and replaces previous getValue calls with getInt calls.
While this changes updates the storage type, it does not update all constant folding calls.

This is done by changing Type to be a POD interface around an underlying pointer storage and adding in-class support for isa/dyn_cast/cast.
