Most builtins in omp-builtins.def is marked as LEAF. At a glance,
that's surprising but looking at the functions, it turns out
that most of them just call 'gomp_thread ()' which is a simple
inline function such that no function call remains.
However, that's not true for all - and omp_get_mapped_ptr and
omp_getinterop_int really do more.
(The other one is an accidental change of mine, which I somehow
missed: omp_is_initial_device in the library returns a constant
and is already simplified in the compiler. Thus, it really
doesn't call any other function.)
Comments before I commit this patch, planed for later today?

omp-builtins.def: Leaf attribute fixes to omp_{is_initial_device,get_{mapped_ptr,interop_int}}
gcc/ChangeLog:
* omp-builtins.def (BUILT_IN_OMP_IS_INITIAL_DEVICE): Re-add LEAF
to the attributes.
(BUILT_IN_OMP_GET_MAPPED_PTR, BUILT_IN_OMP_GET_INTEROP_INT): Remove
LEAF from the attributes as functions are called.
