isSafeToExpand() for addrecs depends on whether the SCEVExpander
will be used in CanonicalMode. At least one caller currently gets
this wrong, resulting in PR50506.
Fix this by a) making the CanonicalMode argument on the freestanding
functions required and b) adding member functions on SCEVExpander
that automatically take the SCEVExpander mode into account. We can
use the latter variant nearly everywhere, and thus make sure that
there is no chance of CanonicalMode mismatch.

Add a new preparation pattern in PPCLoopInstFormPrep pass to reduce register

This is a follow-up of D105872. Now we are able to prepare for update
form with non-const increment.

PPCLoopInstrFormPrep pass now can prepare for load store instructions
in a loop whose increment is not a constant integer.

Pointee types are going away soon.
For this, we mostly just care about store/load types, which are already
available without the pointee types. The other intrinsics always use
i8*.

When you try to define a new DEBUG_TYPE in a header file, DEBUG_TYPE
definition defined around the #includes in files include it could
result in redefinition warnings even compile errors.

On PPC, the vector pair instructions are independent from MMA.
This patch renames the vector pair LLVM intrinsics and Clang builtins to replace the _mma_ prefix by _vsx_ in their names.
We also move the vector pair type/intrinsic/builtin tests to their own files.

SCEVExpander modifies the underlying function so it is more suitable in
Transforms/Utils, rather than Analysis. This allows using other
transform utils in SCEVExpander.
This patch was originally committed as b8a3c34eee06, but broke the
modules build, as LoopAccessAnalysis was using the Expander.
The code-gen part of LAA was moved to lib/Transforms recently, so this
patch can be landed again.

Summary:
This is NFC code clean work after D67088. In that patch, we extend loop instructions prep for ds/dq form.
This patch only changes the file name PPCLoopPreIncPrep.cpp to PPCLoopInstrFormPrep.cpp for better reviewing of the content change of file PPCLoopInstrFormPrep.cpp.
