libgomp plugins: Remove the (OpenACC) avail function.
This idea has been to use this to see whether a class of devices is generally
available, without determining the exact number of devices that are available.
Such a distinction probably doesn't make too much sense; in the following, we'd
like to use one device anyway.
Inline the few users.
libgomp/
* target.h (struct ACC_dispatch_t): Remove avail_func. Update all
users.
* oacc-host.c (openacc_avail): Likewise.
* plugin-nvptx.c (PTX_avail, openacc_avail): Likewise.
* libgomp.texi (acc_get_num_devices): Revise.
