When compiling with the restriction No_Exception_Propagation, GNAT compiler
may issue a warning about exceptions not being propagated. This warning is
useless and confusing to users for GNATprove analysis, as GNATprove
precisely detects possible exceptions, so disable the warning in that mode.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* gnat1drv.adb (Gnat1drv): Do not issue warning about exception not
	being propagated in GNATprove mode.
