[COMMITTED] ada: Generate missing object decls for adainit/adafinal registration calls

["Marc Poulhiès" <poulhies@adacore.com>]

From: Steve Baird <baird@adacore.com>

A previous change on this ticket introduced calls to CUDA_Register_Function
for adainit and adafinal, but failed to introduce declarations for the
C string variables that are initialized and then passed as actual parameters
in this call. Provide the missing declarations (and, incidentally, change
the names of the two variables).

gcc/ada/

	* bindgen.adb: Introduce two new string constants for the names of
	the C-String variables that are assigned the names for adainit and
	adafinal. Replace string literals in Gen_CUDA_Init with references
	to these constants. In Gen_CUDA_Defs, generate C-String variable
	declarations where these constants are the names of the variables.

Tested on x86_64-pc-linux-gnu, committed on master.
