Fix undefined warning messages in GCC 6.
GCC 6 puts out warnings in a different location then GCC 5. Move the DIAG macros so that the warnings are supressed for both compilers. ChangeLog: * soft-fp/fmasf4.c: Add include of sys/cdefs.h. Move DIAG_PUSH_NEEDS_COMMENT, DIAG_IGNORE_NEEDS_COMMENT to front of file, move DIAG_POP_NEEDS_COMMENT to end of file. * soft-fp/fmadf4.c: Ditto. * soft-fp/fmatf4.c: Ditto.
