libgomp: Ensure that either gomp_team is properly aligned [PR102838]
struct gomp_team has struct gomp_work_share array inside of it.
If that latter structure has 64-byte aligned member in the middle,
the whole struct gomp_team needs to be 64-byte aligned, but we weren't
allocating it using gomp_aligned_alloc.
This patch fixes that, except that on gcn team_malloc is special, so
I've instead decided at least for now to avoid using aligned member
and use the padding instead on gcn.

PR libgomp/102838
* libgomp.h (GOMP_USE_ALIGNED_WORK_SHARES): Define if
GOMP_HAVE_EFFICIENT_ALIGNED_ALLOC is defined and __AMDGCN__ is not.
(struct gomp_work_share): Use GOMP_USE_ALIGNED_WORK_SHARES instead
of
GOMP_HAVE_EFFICIENT_ALIGNED_ALLOC.
* work.c (alloc_work_share, gomp_work_share_start): Likewise.
* team.c (gomp_new_team): If GOMP_USE_ALIGNED_WORK_SHARES, use
gomp_aligned_alloc instead of team_malloc.
