Marcel Vollweiler bbb7f8604e C, C++, Fortran, OpenMP: Add 'has_device_addr' clause to 'target' construct. 
This patch adds the 'has_device_addr' clause to the OpenMP 'target' construct
which was introduced in OpenMP 5.1 (OpenMP API 5.1 specification pp. 197ff):

	has_device_addr(list)

"The has_device_addr clause indicates that its list items already have device
addresses and therefore they may be directly accessed from a target device.
If the device address of a list item is not for the device on which the target
region executes, accessing the list item inside the region results in
unspecified behavior. The list items may include array sections." (p. 200)

"A list item may not be specified in both an is_device_ptr clause and a
has_device_addr clause on the directive." (p. 202)

"A list item that appears in an is_device_ptr or a has_device_addr clause must
not be specified in any data-sharing attribute clause on the same target
construct." (p. 203)
