C/C++ OpenACC: acc_pcopyin, acc_pcreate

Browse Source 
libgomp/
	* openacc.h (acc_pcopyin, acc_pcreate): Provide prototypes instead
	of preprocessor definitions.
	* libgomp.h (strong_alias): Guard by "#ifdef
	HAVE_ATTRIBUTE_ALIAS".
	* oacc-mem.c: Provide "acc_pcreate" as alias for
	"acc_present_or_create", and "acc_pcopyin" as alias for
	"acc_present_or_copyin".
	* libgomp.map: New version "OACC_2.0.1".
	(OACC_2.0.1): Add "acc_pcopyin", and "acc_pcreate".
	* testsuite/libgomp.oacc-c-c++-common/lib-38.c: Remove, merging
	its content into...
	* testsuite/libgomp.oacc-c-c++-common/lib-32.c: ... this file.
	Extend testing.
