	* exp_ch6.adb (Expand_Call): When inlining a call to a function
	declared in a package instance, locate the instance node of the
	package after the actual package declaration. skipping over
	pragmas that may have been introduced when the generic unit
	carries aspects that are transformed into pragmas.

	* s-memory.adb (Alloc, Realloc): Move checks
	for Size = 0 or size_t'Last into the Result = System.Null_Address
	path for efficiency. Improve comments (based on actual C language
	requirements for malloc).
	* exp_util.adb (Build_Allocate_Deallocate_Proc): Optimize the
	case where we are using the default Global_Pool_Object, and we
	don't need the heavy finalization machinery.
