Currently, pattern based optimizations of Polly can identify matrix multiplication and optimize it according to BLIS matmul optimization pattern (see ScheduleTreeOptimizer for details). This patch makes optimizations based on pattern matching be enabled by default. Reviewed-by: Tobias Grosser <tobias@grosser.es> Differential Revision: https://reviews.llvm.org/D30293 llvm-svn: 295958
