Florian Hahn 6d18c2067e [Matrix] Update load/store intrinsics.
This patch adjust the load/store matrix intrinsics, formerly known as
llvm.matrix.columnwise.load/store, to improve the naming and allow
passing of extra information (volatile).

The patch performs the following changes:
 * Rename columnwise.load/store to column.major.load/store. This is more
   expressive and also more in line with the naming in Clang.
 * Changes the stride arguments from i32 to i64. The stride can be
   larger than i32 and this makes things more uniform with the way
   things are handled in Clang.
 * A new boolean argument is added to indicate whether the load/store
   is volatile. The lowering respects that when emitting vector
   load/store instructions
 * MatrixBuilder is updated to require both Alignment and IsVolatile
   arguments, which are passed through to the generated intrinsic. The
   alignment is set using the `align` attribute.

The changes are grouped together in a single patch, to have a single
commit that breaks the compatibility. We probably should be fine with
updating the intrinsics, as we did not yet officially support them in
the last stable release. If there are any concerns, we can add
auto-upgrade rules for the columnwise intrinsics though.

Florian Hahn e02c964969 [Matrix] Specify missing alignment in tests (NFC).
Some tests were missing alignment info. Subsequent changes properly
preserve the set alignment. Set it properly beforehand, to avoid
unnecessary test changes.

It also updates cases where an alignment of 16 was specified, instead of
the vector element type alignment.

Florian Hahn 3631239b26 [Matrix] Update check lines for strided intrinsics (NFC).
This re-generates some check lines, after the naming of values got
improved, to reduce the size of diffs in follow-on patches.

Florian Hahn 7adf6644f5 [Matrix] Propagate and use shape information for loads.
This patch extends to shape propagation to also include load
instructions and implements shape aware lowering for vector loads.

Florian Hahn 459ad8e97e [Matrix] Implement back-propagation of shape information.
This patch extends the shape propagation for matrix operations to also
propagate the shape of instructions to their operands.
