It might be better to benchmark MPI codes without synchronization because of overhead of timing individual steps

Setting inv_dsx etc explicitly is no longer required as they are set to default values in acc/stdlib/stdderiv.h

Major improvement: uniforms can now be set to default values. The syntax is the same as for setting any other values, f.ex. 'uniform Scalar a = 1; uniform Scalar b = 0.5 * a;'. Undefined uniforms are still allowed, but in this case the user should load a proper value into it during runtime. Default uniform values can be overwritten by calling any of the uniform loader funcions (like acDeviceLoadScalarUniform). Improved also error checking. Now there are explicit warnings if the user tries to load an invalid value into a device constant.

mpitest now gives a warning instead of a compilation failure if MPI is not enabled
