This patch shows the changes to polybench/symm to add checkFP between a version compiled with default flags and another version compiled at optnone + fp-contract=off.

With clang top of tree, compiling this kernel with __attribute__((optnone)) and outputing the contents of the C_StrictFP array does not match the reference output.
Furthermore, when the test-suite is configured with CFLAGS = -Ofast this test only passes for FP_ABSTOLERANCE=10.
