C/C++ OpenACC: acc_pcopyin, acc_pcreate
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.
