[RemoveDIs][DebugInfo] Handle DPVAssign in most transforms (#78986) 
This patch trivially updates various opt passes to handle DPVAssigns. In
all cases, this means some combination of generifying existing code to
handle DPValues and DbgAssignIntrinsics, iterating over DPValues where
previously we did not, or duplicating code for DbgAssignIntrinsics to
the equivalent DPValue function (in inlining and salvageDebugInfo).

4ece50737d [Assignment Tracking][NFC] Replace LLVM command line option with a module flag 
Remove LLVM flag -experimental-assignment-tracking. Assignment tracking is
still enabled from Clang with the command line -Xclang
-fexperimental-assignment-tracking which tells Clang to ask LLVM to run the
pass declare-to-assign. That pass converts conventional debug intrinsics to
assignment tracking metadata. With this patch it now also sets a module flag
debug-info-assignment-tracking with the value `i1 true` (using the flag conflict
rule `Max` since enabling assignment tracking on IR that contains only
conventional debug intrinsics should cause no issues).

Update the docs and tests too.

139e08efc5 [Assignment Tracking][23/*] Account for assignment tracking in SLP Vectorizer 
The Assignment Tracking debug-info feature is outlined in this RFC:

https://discourse.llvm.org/t/
rfc-assignment-tracking-a-better-way-of-specifying-variable-locations-in-ir

The SLP-Vectorizer can merge a set of scalar stores into a single vectorized
store. Merge DIAssignID intrinsics from the scalar stores onto the new
vectorized store.
