[IR] Enable opaque pointers by default

This enabled opaque pointers by default in LLVM. The effect of this
is twofold:

* If IR that contains *neither* explicit ptr nor %T* types is passed
to tool

[IR] Enable opaque pointers by default

This enabled opaque pointers by default in LLVM. The effect of this
is twofold:

* If IR that contains *neither* explicit ptr nor %T* types is passed
to tools, we will now use opaque pointer mode, unless
-opaque-pointers=0 has been explicitly passed.
* Users of LLVM as a library will now default to opaque pointers.
It is possible to opt-out by calling setOpaquePointers(false) on
LLVMContext.

A cmake option to toggle this default will not be provided. Frontends
or other tools that want to (temporarily) keep using typed pointers
should disable opaque pointers via LLVMContext.

[IROutliner] Ensure that incoming blocks of PHINodes are included in the unique numbering gneration for phi nodes for each exit path

[IROutliner] Ensure that incoming blocks of PHINodes are included in the unique numbering gneration for phi nodes for each exit path

Issue: https://github.com/llvm/llvm-project/issues/54431

PHINodes that need to be generated to accommodate a PHINode outside the region due to different output paths need to have their own numbering to determine the number of output schemes required to properly handle all the outlined regions. This numbering was previously only determined by the order and values of the incoming values, as well as the parent block of the PHINode. This adds the incoming blocks to the calculation of a hash value for these PHINodes as well, and the supporting infrastructure to give each block in a region a corresponding canonical numbering.
