Michael Kruse a56bd7dec8 [Polly][Matmul] Re-pack A in every iteration.
Packed_A must be copied repeatedly, not just for the first iteration of
the outer tile.

This fixes llvm.org/PR50557

Roman Gareev 0956a606ff Disable the Loop Vectorizer in case of GEMM
Currently, in case of GEMM and the pattern matching based optimizations, we
use only the SLP Vectorizer out of two LLVM vectorizers. Since the Loop
Vectorizer can get in the way of optimal code generation, we disable the Loop
Vectorizer for the innermost loop using mark nodes and emitting the
corresponding metadata.

Roman Gareev 3d4eae31ea Use the size of the widest type of the matrix multiplication operands
The size of the operands type is the one of the parameters required
to determine the BLIS micro-kernel. We get the size of the widest type
of the matrix multiplication operands in case there are several
different types.
